gr-qc/0609017 [abs, ps, pdf, other] :: Title: Density Perturbations for Running Cosmological Constant
Authors: Julio C. Fabris, Ilya L. Shapiro, Joan Sola
Comments: LaTeX, 19 pages, 5 figures

The dynamics of density and metric perturbations is investigated for the previously developed model where the decay of the vacuum energy into matter (or vice versa) is due to the renormalization group running of the cosmological constant term (CC). The dynamics of the CC depends on the single parameter \nu which characterizes the running of the CC produced by the mass spectrum of the unknown high energy theory below the Planck scale. The sign of \nu indicates whether bosons or fermions dominate in the running of the CC. The numerical analysis of the perturbations shows that for \nu in the range -10^{-6}< \nu<10^{-6} the compatibility with the LSS data is excellent. The \nu>0 region 10^{-6}<\nu< 10^{-5} cannot be significantly excluded by the LSS data alone. But for |\nu|>10^{-4} the form of the spectrum severely contradicts the observational data, most noticeably for \nu<0. From the particle physics viewpoint, the value |\nu|=10^{-6} corresponds to the ``desert'' in the mass spectrum above the GUT scale M_X\sim 10^{16} GeV. Our results are in qualitative agreement with other known models permitting vacuum-matter energy exchange. However, in contrast to previous approaches, we present here for the first time a full fledged calculation of the matter power spectrum of perturbations for a FLRW model with running cosmological constant. It appears to be the most efficient method to discover a possible scale dependence of the vacuum energy.

Authors: Lorenzo Iorio
Comments: LaTex, 12 pages, no figures, 4 tables, 26 references
Subj-class: General Relativity and Quantum Cosmology; Space Physics

In this paper we dynamically determine the mass of the Kuiper Belt Objects by exploiting the latest observational determinations of the orbital motions of the inner planets of the Solar System. Our result, in units of terrestrial masses, is 0.033 +/- 0.115 by modelling the Classical Kuiper Belt Objects as an ecliptic ring of finite thickness. A two-rings model yields for the Resonant Kuiper Belt Objects a value of 0.018 +/- 0.063. Such figures are consistent with recent determinations obtained with ground and space-based optical techniques. Some implications for precise tests of Einsteinian and post-Einsteinian gravity are briefly discussed.
gr-qc/0609024 [abs, ps, pdf, other] :: Title: Observation of Incipient Black Holes and the Information Loss Problem
Authors: Tanmay Vachaspati, Dejan Stojkovic, Lawrence M. Krauss
Comments: 13 pages; 8 figures

(Abridged) We study the (quantum) formation of black holes by spherical domain wall collapse as seen by an asymptotic observer. Using the Wheeler-de Witt equation to describe the collapsing spherical domain wall, we show that the black hole takes an infinite time to form for the asymptotic observer in the quantum theory, just as in the classical treatment. We argue that such observers will therefore see a compact object but never see effects associated with the formation of an event horizon. To explore what signals such observers will see, we study radiation of a scalar quantum field in the collapsing domain wall background. Both the functional Schrodinger approach and an adaptation of Hawking's original calculation indicate that there is radiation from the collapsing domain wall. The radiation may be relevant should gravitational collapse in particle collisions be induced at the LHC if low scale gravity is observed. The radiation is non-thermal, and the total flux radiated diverges when backreaction of the radiation on the collapsing wall is ignored. We discuss the conjecture, based on our analysis, that the domain wall will evaporate completely by non-thermal radiation during the collapse process and never form a black hole or an event horizon. Whether or not there is ``evaporation before formation'' no horizon down which information may be lost forms in any finite time, so that gravitational collapse appears to preserve unitarity. Thus, our findings may resolve the black hole information loss problem. This fact is suggestive of a possible superselection rule separating universes with no initial black hole event horizons from those in which these are initially present.
gr-qc/0609026 [abs, ps, pdf, other] :: Title: Spectroscopy of Cosmic topology
Authors: Tarun Souradeep (IUCAA)
Comments: 8 pages, 3 figures; Invited contribution to a special issue of IJP in memory of Prof. A.K. Raychaudhuri

Einstein's theory of gravitation that governs the geometry of space-time, coupled with spectacular advance in cosmological observations, promises to deliver a `standard model' of cosmology in the near future. However, local geometry of space constrains, but does not dictate the topology of the cosmos. hence, Cosmic topology has remained an enigmatic aspect of the `standard model' of cosmology. Recent advance in the quantity and quality of observations has brought this issue within the realm of observational query. The breakdown of statistical homogeneity and isotropy of cosmic perturbations is a generic consequence of non trivial cosmic topology arising from to the imposed `crystallographic' periodicity on the eigenstates of the Laplacian. The sky maps of Cosmic Microwave Background (CMB) anisotropy and polarization most promising observations that would carry signatures of a violation of statistical isotropy and homogeneity. Hence, a measurable spectroscopy of cosmic topology is made possible using the Bipolar power spectrum (BiPS) of the temperature and polarization that quantifies violation of statistical isotropy.
gr-qc/0609028 [abs, ps, pdf, other] :: Title: A brief survey of LISA sources and science
Authors: Scott A. Hughes
Comments: 8 pages, 2 figures, for the Proceedings of the Sixth International LISA Symposium

LISA is a planned space-based gravitational-wave (GW) detector that would be sensitive to waves from low-frequency sources, in the band of roughly $(0.03 - 0.1) {\rm mHz} \lesssim f \lesssim 0.1 {\rm Hz}$. This is expected to be an extremely rich chunk of the GW spectrum -- observing these waves will provide a unique view of dynamical processes in astrophysics. Here we give a quick survey of some key LISA sources and what GWs can uniquely teach us about these sources. Particularly noteworthy science which is highlighted here is the potential for LISA to track the moderate to high redshift evolution of black hole masses and spins through the measurement of GWs generated from massive black hole binaries (which in turn form by the merger of galaxies and protogalaxies). Measurement of these binary black hole waves has the potential to determine the masses and spins of the constituent black holes with percent-level accuracy or better, providing a unique high-precision probe of an aspect of early structure growth. This article is based on the ``Astrophysics Tutorial'' talk given by the author at the Sixth International LISA Symposium.
hep-ph/0608186 [abs, ps, pdf, other] :: Title: Unveiling Chameleons in Tests of Gravitational Inverse-Square Law
Authors: Amol Upadhye, Steven S. Gubser, Justin Khoury
Comments: 20 pages, 10 figures

Scalar self interactions are known to weaken considerably the current constraints on scalar-mediated fifth forces. We consider a scalar field with a quartic self interaction and gravitation-strength Yukawa couplings to matter particles. After discussing the phenomenology of this scalar field, we assess the ability of ongoing and planned experiments to detect the fifth force mediated by such a field. Assuming that the quartic and matter couplings are of order unity, the current-generation Eot-Wash experiment at the University of Washington will be able to explore an interesting subset of parameter space. The next-generation Eot-Wash experiment is expected to be able to detect, or to rule out, the fifth force due to such a scalar with unit quartic and matter couplings at the 3 sigma confidence level.
hep-th/0608211 [abs, ps, pdf, other] :: Title: Surface Casimir densities and induced cosmological constant in higher dimensional braneworlds
Authors: Aram A. Saharian
Comments: 21 pages, 5 figures, REVTeX, references added

We investigate the vacuum expectation value of the surface energy-momentum tensor for a massive scalar field with general curvature coupling parameter obeying the Robin boundary conditions on two codimension one parallel branes in a (D+1)-dimensional background spacetime $AdS_{D_{1}+1}\times \Sigma $ with a warped internal space $\Sigma $. These vacuum densities correspond to a gravitational source of the cosmological constant type for both subspaces of the branes. Using the generalized zeta function technique in combination with contour integral representations, the surface energies on the branes are presented in the form of the sum of single brane and second brane induced parts. For the geometry of a single brane both regions, on the left and on the right of the brane, are considered. At the physical point the corresponding zeta functions contain pole and finite contributions. For an infinitely thin brane taking these regions together, in odd spatial dimensions the pole parts cancel and the total zeta function is finite. The renormalization procedure for the surface energies and the structure of the corresponding counterterms are discussed. The parts in the surface densities generated by the presence of the second brane are finite for all nonzero values of the interbrane separation and are investigated in various asymptotic regions of the parameters. In particular, it is shown that for large distances between the branes the induced surface densities give rise to an exponentially suppressed cosmological constant on the brane. The total energy of the vacuum including the bulk and boundary contributions is evaluated by the zeta function technique and the energy balance between separate parts is discussed.

Authors: Alexander Kusenko
Comments: 4 pages, one figure

We identify the range of parameters for which the sterile neutrinos can simultaneously explain the cosmological dark matter and the observed velocities of pulsars. To satisfy all cosmological bounds, the relic sterile neutrinos must be produced sufficiently cold. This is possible in a class of models with a gauge-singlet Higgs boson, coupled to the neutrinos as a singlet Majoron. Sterile dark matter can be detected by the x-ray telescopes. The presence of the singlet Majoron in the Higgs sector can be tested at the LHC.

gr-qc/0609033 [abs, ps, pdf, other] :: Title: Spinor Theory of Gravity
Authors: M. Novello

The proposal of this work is to provide an answer to the following question: is it possible to treat the metric of space-time - that in General Relativity (GR) describes the gravitational interaction - as an effective geometry? In other words, to obtain the dynamics of the metric tensor as a consequence of the dynamics of other fields. In this work we will use a slight modfication of the non-linear equation of motion of a spinor field proposed some years ago by Heisenberg, although in a completely distinct context, to obtain a field theory that provides a framework equivalent to the way GR represents the gravitational interaction. In particular we exhibit a solution of the equations of motion that represents the gravitational field of a compact object and compare it with the corresponding Schwarzschild solution of General Relativity.
hep-ph/0607237 [abs, ps, pdf, other] :: Title: Modular inflation and the curvaton
Authors: George Lazarides (Aristotle U., Thessaloniki)
Comments: 12 pages including 1 figure, uses aipproc.cls, references added, talk given at Cairo International Conference on High Energy Physics (CICHEP II), German University in Cairo (GUC), Egypt, 14-17 January 2006 (to appear in the proceedings)

Supersymmetric Peccei-Quinn models which provide a suitable candidate for the curvaton field are studied. These models also solve the mu problem, while generating the Peccei-Quinn scale dynamically. The curvaton is a pseudo Nambu-Goldstone boson corresponding to an angular degree of freedom orthogonal to the axion. Its order parameter increases substantially following a phase transition during inflation. This results in a drastic amplification of the curvaton perturbations. Consequently, these models are able to accommodate low-scale inflation with Hubble parameter at the TeV scale such as modular inflation. We find that modular inflation with the orthogonal axion as curvaton can indeed account for the observations for natural values of the parameters. In particular, the spectral index can easily be made adequately lower than unity in accord with the recent data.

The nuclear physics input from the 3He(alpha,gamma)7Be cross section is a major uncertainty in the fluxes of 7Be and 8B neutrinos from the Sun predicted by solar models and in the 7Li abundance obtained in big-bang nucleosynthesis calculations. The present work reports on a new precision experiment using the activation technique at energies directly relevant to big-bang nucleosynthesis. Previously such low energies had been reached experimentally only by the prompt-gamma technique and with inferior precision. Using a windowless gas target, high beam intensity and low background gamma-counting facilities, the 3He(alpha,gamma)7Be cross section has been determined at 127, 148 and 169 keV center-of-mass energy with a total uncertainty of 4%. The sources of systematic uncertainty are discussed in detail. The present data can be used in big-bang nucleosynthesis calculations and to constrain the extrapolation of the 3He(alpha,gamma)7Be astrophysical S-factor to solar energies.

gr-qc/0607050 [abs, ps, pdf, other] :: Title: Area evolution, bulk viscosity and entropy principles for dynamical horizons
Authors: Eric Gourgoulhon, Jose Luis Jaramillo (LUTH, Observatoire de Paris)
Comments: Some references added, 5 pages, Phys. Rev. D, in press

We derive from Einstein equation an evolution law for the area of a trapping or dynamical horizon. The solutions to this differential equation show a causal behavior. Moreover, in a viscous fluid analogy, the equation can be interpreted as an energy balance law, yielding to a positive bulk viscosity. These two features contrast with the event horizon case, where the non-causal evolution of the area and the negative bulk viscosity require teleological boundary conditions. This reflects the local character of trapping horizons as opposed to event horizons. Interpreting the area as the entropy, we propose to use an area/entropy evolution principle to select a unique dynamical horizon and time slicing in the Cauchy evolution of an initial marginally trapped surface.
gr-qc/0609041 [abs, ps, pdf, other] :: Title: Charged massive particle at rest in the field of a Reissner-Nordstr\"om black hole
Authors: Donato Bini, Andrea Geralico, Remo Ruffini
Comments: 42 pages, 3 eps figures, revtex macros

The interaction of a Reissner-Nordstr\"om black hole and a charged massive particle is studied in the framework of perturbation theory. The particle backreaction is taken into account, studying the effect of general static perturbations of the hole following the approach of Zerilli. The solutions of the combined Einstein-Maxwell equations for both perturbed gravitational and electromagnetic fields at first order of the perturbation are exactly reconstructed by summing all multipoles, and are given explicit closed form expressions. The existence of a singularity-free solution of the Einstein-Maxwell system requires that the charge to mass ratios of the black hole and of the particle satisfy an equilibrium condition which is in general dependent on the separation between the two bodies. If the black hole is undercritically charged (i.e. its charge to mass ratio is less than one), the particle must be overcritically charged, in the sense that the particle must have a charge to mass ratio greater than one. If the charge to mass ratios of the black hole and of the particle are both equal to one (so that they are both critically charged, or "extreme"), the equilibrium can exist for any separation distance, and the solution we find coincides with the linearization in the present context of the well known Majumdar-Papapetrou solution for two extreme Reissner-Nordstr\"om black holes. In addition to these singularity-free solutions, we also analyze the corresponding solution for the problem of a massive particle at rest near a Schwarzschild black hole, exhibiting a strut singularity on the axis between the two bodies. The relations between our perturbative solutions and the corresponding exact two-body solutions belonging to the Weyl class are also discussed.
hep-ph/0609086 [abs, ps, pdf, other] :: Title: Complex Hybrid Inflation and Baryogenesis
Authors: David Delepine, Carlos Martinez, L. Arturo Urena-Lopez
Comments: 4 RevTex pages, no figures

We propose a hybrid inflation model with a complex waterfall field which contains an interaction term that breaks the U(1) global symmetry associated to the waterfall field charge. We show that the asymmetric evolution of the real and imaginary parts of the complex field during the phase transition at the end of inflation translates into a charge asymmetry. The latter strongly depends on the VEV of the waterfall field, whose value should be around the GUT scale in order to fulfill the observational constraints.

Authors: M.B. Gay Ducati, M.M. Machado, M.V.T. Machado
Comments: 16 pages, 7 figures

We present an exploratory QCD analysis of the neutrino structure functions in charged current DIS using the color dipole formalism. The corresponding dipole cross sections are taken from recent phenomenological/theoretical studies in deep inelastic inclusive production. The theoretical predictions are compared to the available experimental results in the small-x region. In particular, the behavior of the structure functions on the boson virtuality and the role played by the nuclear shadowing corrections are investigated. It is demonstrated that small-x neutrino-hadron cross section exhibits geometric scaling property as in lepton-hadron processes.
nucl-th/0609026 [abs, ps, pdf, other] :: Title: Low Densities Instability of Relativistic Mean Field Models
Authors: A. Sulaksono, T. Mart
Comments: 25 pages, 10 figures, submitted to Phys. Rev. C

The effects of the symmetry energy softening of the relativistic mean field (RMF) models on the properties of matter with neutrino trapping are investigated. It is found that the effects are less significant than those in the case without neutrino trapping. The weak dependence of the equation of state on the symmetry energy is shown as the main reason of this finding. Using different RMF models the dynamical instabilities of uniform matters, with and without neutrino trapping, have been also studied. The interplay between the dominant contribution of the variation of matter composition and the role of effective masses of mesons and nucleons leads to higher critical densities for matter with neutrino trapping. Furthermore, the predicted critical density is insensitive to the number of trapped neutrinos as well as to the RMF model used in the investigation. It is also found that additional nonlinear terms in the Horowitz-Piekarewicz and Furnstahl-Serot-Tang models prevent another kind of instability, which occurs at relatively high densities. The reason is that the effective sigma meson mass in their models increases as a function of the matter density.

Authors: Ishwaree P. Neupane
Comments: 4 pages, RevTeX4

We find cosmological solution corresponding to compactification of 10d supergravity on a warped conifold that easily circumvents Gibbons's original "no-go" theorem, providing new perspectives for the study of supergravity or superstring theory in cosmological backgrounds. With stabilized volume moduli, the model can explain a physical universe undergoing an accelerated expansion in the 4d Einstein frame, for a sufficiently long time. The solution found in the limit that the warp factor dependent on the radial coordinate $y$ is extremized (giving a constant warping) is smooth and it supports a flat four-dimensional Friedmann-Robertson-Walker cosmology undergoing a period of accelerated expansion with slowly rolling or stabilized volume moduli.

This is a continuation of our previous works [1] [2] on the error estimate of the averaging technique, for systems with one fast angular variable. In the cited papers a general method (of mixed analytical and numerical type) has been introduced to obtain precise, fully quantitative estimates on the averaging error. Here, this procedure is applied to the motion of a satellite in a polar orbit around an oblate planet, retaining only the J2 term in the multipole expansion of the gravitational potential. To exemplify the method, the averaging errors are estimated for the data corresponding to two Earth satellites; for a very large number of orbits, computation of our estimators is much less expensive than the direct numerical solution of the equations of motion.
