Title: Higher Derivative Scalar Field Theory in the First Order Formalism
Authors: S. I. Kruglov
Comments: 15 pages, invited paper for the Special Issue of Annales Fond. Broglie dedicated to Ettore Majorana

The scalar field theory with higher derivatives is considered in the first order formalism. The field equation of the forth order describes scalar particles possessing two mass states. The first order relativistic wave equation in the 10-dimensional matrix form is derived. We find the relativistically invariant bilinear form and corresponding Lagrangian. The canonical energy-momentum tensor and density of the electromagnetic current are obtained. Dynamical and non-dynamical components of the wave function are separated and the quantum-mechanical Hamiltonian is found. Projection operators extracting solutions of field equations for definite energy and different mass states of particles are obtained. The canonical quantization of scalar fields with two mass states is performed, and propagators are found in the formalism considered.

Title: Semiclassical (QFT) and Quantum (String) anti - de Sitter Regimes: New Results
Authors: A. Bouchareb, M. Ramon Medrano, N. G. Sanchez
Comments: Comments 26 pages; no figures

We compute the quantum string entropy S_s(m, H) from the microscopic string density of states of mass m in Anti de Sitter space-time. For high m, (high Hm -->c/\alpha'), no phase transition occurs at the Anti de Sitter string temperature T_{s} which is higher than the flat space (Hagedorn) temperature t_{s}. (the Hubble constant H acts as producing a smaller string constant and thus, a higher tension). T_s is the precise quantum dual of the semiclassical (QFT) Anti de Sitter temperature scale . We compute the quantum string emission by a black hole in Anti de Sitter space-time (bhAdS). In the early evaporation stage, it shows the QFT Hawking emission with temperature T_{sem~bhAdS}, (semiclassical regime). For T_{sem~bhAdS}--> T_{s}, it exhibits a phase transition into a Anti de Sitter string state. New string bounds on the black hole emerge in the bhAdS string regime. We find a new formula for the full (quantum regime included) Anti de Sitter entropy S_{sem}, as a function of the usual Bekenstein-Hawking entropy S_{sem}^(0). For low H (semiclassical regime), S_{sem}^(0) is the leading term but for high H (quantum regime), no phase transition operates, in contrast to de Sitter space, and the entropy S_{sem} is very different from the Bekenstein-Hawking term S_{sem}^(0).

Title: Rayleigh-Taylor turbulence is nothing like Kolmogorov's in the self similar regime
Authors: Olivier Poujade
Comments: 4 pages, 1 figure, submitted to PRL
Subj-class: Plasma Physics; Fluid Dynamics

An increasing number of numerical simulations and experiments describing the turbulent spectrum of Rayleigh-Taylor (RT) mixing layers came to light over the past few years. Results reported in recent studies allow to rule out a turbulence {\it \`a la Kolmogorov} as a mechanism acting on a self similar RT turbulent mixing layer. A different mechanism is presented, which complies with both numerical and experimental results and relates RT flow to other buoyant flows.

Title: Branes: cosmological surprise and observational deception
Authors: Stephane Fay
Comments: 29 pages, 25 figures
Journal-ref: A&A 452 (2006) 781-794

Using some supernovae and CMB data, we constrain the Cardassian, Randall-Sundrum, and Dvali-Gabadadze-Porrati brane-inspired cosmological models. We show that a transient acceleration and an early loitering period are usually excluded by the data. Moreover, the three models are equivalent to some usual quintessence/ghost dark energy models defined by a barotropic index $\gamma_\phi$ depending on the redshift. We calculate this index for each model and show that they mimic a universe close to a $\Lambda CDM$ model today.

Title: Higgs instability in gapless superfluidity/superconductor
Authors: Ioannis Giannakis, Defu Hou, Mei Huang, Hai-cang Ren
Comments: 4 pages, 1 figure
Subj-class: High Energy Physics - Phenomenology; Superconductivity

We examined in this letter the Higgs instability in the gapless superfluidity/superconductivity, which is in addition to the (chromo)magnetic instability related to the Nambu-Goldstone fields. While the latter may induce a LOFF-like state, the Higgs instability favors spatial inhomogeneity and cannot be removed without a long range force. In case of g2SC the Higgs instability can be partially removed by the electric Coulomb energy. But this does not exclude the possibility of its completely removal in other exotic states such as gCFL.

Title: The Price of WMAP Inflation in Supergravity
Authors: J. Ellis, Z. Lalak, S. Pokorski, K. Turzynski
Comments: 15 pages, 6 figures, plain Latex

The three-year data from WMAP are in stunning agreement with the simplest possible quadratic potential for chaotic inflation, as well as with new or symmetry-breaking inflation. We investigate the possibilities for incorporating these potentials within supergravity, particularly of the no-scale type that is motivated by string theory. Models with inflation driven by the matter sector may be constructed in no-scale supergravity, if the moduli are assumed to be stabilised by some higher-scale dynamics and at the expense of some fine-tuning. We discuss specific scenarios for stabilising the moduli via either D- or F-terms in the effective potential, and survey possible inflationary models in the presence of D-term stabilisation.

We discuss the status of both cosmological and black hole type singularities in the framework of the brane-world model of gravity. We point out that the Big Bang is not properly understood yet. We also show new features of the gravitational collapse on the brane, the most important being the production of dark energy during the collapse.

Title: A theory of Cosmic Rays
Authors: Arnon Dar, Alvaro De Rujula
Comments: 40 pages, 34 figures

We present a theory of non-solar cosmic rays (CRs) based on a single type of CR source at all energies. The total luminosity of the Galaxy, the broken power-law spectra with their observed slopes, the position of the `knee(s)' and `ankle', and the CR composition and its variation with energy are all predicted in terms of very simple and completely `standard' physics. The source of CRs is extremely `economical': it has only one parameter to be fitted to the ensemble of all of the mentioned data. All other inputs are `priors', that is, theoretical or observational items of information independent of the properties of the source of CRs, and chosen to lie in their pre-established ranges. The theory is part of a `unified view of high-energy astrophysics' --based on the `Cannonball' model of the relativistic ejecta of accreting black holes and neutron stars. If correct, this model is only lacking a satisfactory theoretical understanding of the `cannon' that emits the cannonballs in catastrophic processes of accretion.

Title: Unlayered graphenes in red-giant starsmoke
Authors: Eric Mandell, Nathaniel Hunton, P. Fraundorf
Comments: 8 pages, 10 figs, 31 refs, RevTeX4 cf. this http URL
Subj-class: Materials Science

Electron diffraction, imaging, and energy loss provide evidence for unlayered graphene sheets in the core of certain interstellar graphite onions (from the meteorite Murchison) whose isotopes indicate formation in the atmosphere of late-stage asymptotic giant branch stars (like those which nucleo-synthesized much of the earth's carbon). The data are compared to structural models loosely associated with atom-by-atom, molecule-by-molecule, and dendritic-droplet solidification processes. In this context the observed density, diffraction peak-shapes, and edge-on sheet patterns, along with theoretical limits on time for growth in the presence of outgoing radiation pressure, suggest nucleation of hexagonal sheets from pentagons, perhaps from a supercooled melt. These results warrant a closer examination of specimen structure, the energetics of unlayered graphene nucleation, and processes such as jets in late star atmospheres.

Title: APSIS - an Artificial Planetary System in Space to probe extra-dimensional gravity and MOND
Authors: Varun Sahni, Yuri Shtanov
Comments: 13 pages, revtex, item 9 added in the discussion on page 10, references added

A proposal is made to test Newton's inverse-square law using the perihelion shift of test masses (planets) in free fall within a spacecraft located at the Earth-Sun L2 point. Such an Artificial Planetary System In Space (APSIS) will operate in a drag-free environment with controlled experimental conditions and minimal interference from terrestrial sources of contamination. We demonstrate that such a space experiment can probe the presence of a "hidden" fifth dimension on the scale of a micron, if the perihelion shift of a "planet" can be measured to sub-arc-second accuracy. Some suggestions for spacecraft design are made.

Title: Structure formation on the brane : A mimicry
Authors: Supratik Pal (IIT Kharagpur & Jadavpur University)
Comments: 7 pages. Accepted for publication in Physical Review D

We show how brane-world cosmology with bulk matter can explain structure formation. In this scenario, the nonlocal corrections to the Friedman equations supply a Weyl fluid that can dominate over matter at late times due to the energy-exchange between the brane and the bulk. We demonstrate that the presence of the Weyl fluid radically changes the perturbation equations, which can take care of the fluctuations required to account for the large amount of inhomogeneities observed in the local universe. Further, we show how this Weyl fluid can mimic dark matter. We also investigate the bulk geometry responsible for the scenario.

Title: The Elusive p-air Cross Section
Authors: Martin M. Block
Comments: 15 pages, 6 figures, 2 table,Paper delivered at c2cr2005 Conference, Prague, September 7-13, 2005. Fig. 2 was missing from V1. V3 fixes all figures

For the $\pbar p$ and $pp$ systems, we have used all of the extensive data of the Particle Data Group[K. Hagiwara {\em et al.} (Particle Data Group), Phys. Rev. D 66, 010001 (2002).]. We then subject these data to a screening process, the ``Sieve'' algorithm[M. M. Block, physics/0506010.], in order to eliminate ``outliers'' that can skew a $\chi^2$ fit. With the ``Sieve'' algorithm, a robust fit using a Lorentzian distribution is first made to all of the data to sieve out abnormally high $\delchi$, the individual i$^{\rm th}$ point's contribution to the total $\chi^2$. The $\chi^2$ fits are then made to the sieved data. We demonstrate that we cleanly discriminate between asymptotic $\ln s$ and $\ln^2s$ behavior of total hadronic cross sections when we require that these amplitudes {\em also} describe, on average, low energy data dominated by resonances. We simultaneously fit real analytic amplitudes to the ``sieved'' high energy measurements of $\bar p p$ and $pp$ total cross sections and $\rho$-values for $\sqrt s\ge 6$ GeV, while requiring that their asymptotic fits smoothly join the the $\sigma_{\bar p p}$ and $\sigma_{pp}$ total cross sections at $\sqrt s=$4.0 GeV--again {\em both} in magnitude and slope. Our results strongly favor a high energy $\ln^2s$ fit, basically excluding a $\ln s$ fit. Finally, we make a screened Glauber fit for the p-air cross section, using as input our precisely-determined $pp$ cross sections at cosmic ray energies.

Title: A Seesaw Mechanism in the Higgs Sector
Authors: Xavier Calmet, Josep F. Oliver
Comments: 10 pages

In this letter we revisit the seesaw Higgs mechanism. We show how a seesaw mechanism in a two Higgs doublets model can trigger the electroweak symmetry breaking if at least one of the eigenvalues of the squared mass matrix is negative. We then consider two special cases of interest. In the decoupling scenario, there is only one scalar degree of freedom in the low energy regime. In the degenerate scenario, all five degrees of freedom are in the low energy regime and will lead to observables effects at the LHC. Furthermore, in that scenario, it is possible to impose a discrete symmetry between the doublets that makes the extra neutral degrees of freedom stable. These are thus viable dark matter candidates. We find an interesting relation between the electroweak symmetry breaking mechanism and dark matter.

Title: Supersymmetric Nambu$-$Jona-Lasinio Model on ${\cal N}=1/2$ four-dimensional Non(anti)commutative Superspace
Authors: Tadafumi Ohsaku
Comments: 18 pages

We construct the Lagrangian of the ${\cal N}=1$ four-dimensional generalized supersymmetric Nambu$-$Jona-Lasinio (SNJL) model, which has ${\cal N}=1/2$ supersymmetry (SUSY) on non(anti)commutative superspace. A special attention is paid to the examination on the nonperturbative quantum dynamics: The phenomenon of dynamical-symmetry-breaking/mass-generation on the deformed superspace is investigated. The model Lagrangian and the method of SUSY auxiliary fields of composites are examined in terms of component fields. We derive the effective action, examine it, and solve the gap equation for self-consistent mass parameters.

Title: Evidence of the gravitomagnetic field of Mars
Authors: Lorenzo Iorio
Comments: Latex, 6 pages, 1 figure, 1 table. Accepted for publication in Classical and Quantum Gravity

According to general relativity, the gravitomagnetic Lense-Thirring force of Mars would secularly shift the orbital plane of the Mars Global Surveyor (MGS) spacecraft by an amount of 1.5 m, on average, in the cross-track direction over 5 years. The determined cross-track post-fit residuals of MGS, built up by neglecting just the gravitomagnetic force in the dynamical force models and without fitting any empirical cross-track acceleration which could remove the relativistic signal, amount to 1.6 m, on average, over a 5-years time interval spanning from 10 February 2000 to 14 January 2005. The discrepancy with the predictions of general relativity is 6%.
