Title: Solar System planetary orbital motions and dark matter
Authors:
Lorenzo Iorio
Comments: Latex, 5 pages, 2 tables, no figures, 4 references
In this brief note we explicitly work out the effects that a spherically
symmetric distribution of dark matter would induce on the Keplerian orbital
elements of the Solar System planets and compare them with the latest results
in planetary orbit determination from the EPM2004 ephemerides. It turns out
that the longitudes of perihelia and the mean longitudes are affected by
secular precessions. The resulting upper bounds on dark matter density,
obtained from the EPM2004 formal errors in the determined mean longitude shifts
over 90 years, lie in the range 10^-19-10^-20 g cm^-3 with a peak of 10^-22 g
cm^-3 for Mars. Even if realistic errors on mean longitudes may be one order of
magnitude larger, such results are up to 2-3 orders of magnitude better than
other Solar System-based constraints.

Title: Time-Domain Measurement of Broadband Coherent Cherenkov Radiation

We report on further analysis of coherent microwave Cherenkov impulses
emitted via the Askaryan mechanism from high-energy electromagnetic showers
produced at the Stanford Linear Accelerator Center (SLAC). In this report, the
time-domain based analysis of the measurements made with a broadband (nominally
1-18 GHz) log periodic dipole antenna (LPDA) is described. The theory of a
transmit-receive antenna system based on time-dependent effective height
operator is summarized and applied to fully characterize the measurement
antenna system and to reconstruct the electric field induced via the Askaryan
process. The observed radiation intensity and phase as functions of frequency
were found to agree with expectations from 0.75-11.5 GHz within experimental
errors on the normalized electric field magnitude and the relative phase; 0.039
microV/MHz/TeV and 17 deg, respectively. This is the first time this agreement
has been observed over such a broad bandwidth, and the first measurement of the
relative phase variation of an Askaryan pulse. The importance of validation of
the Askaryan mechanism is significant since it is viewed as the most promissing
way to detect cosmogenic neutrino fluxes at E > 10^15 eV.

Title: Bounds on neutrino masses from baryogenesis in thermal and non-thermal
scenarios
Authors:
Narendra Sahu
Comments: Ph.D thesis (Supervisor: Prof. Urjit A Yajnik), 134 pages
Baryogenesis via leptogenesis is an attractive scenario that links the
physics of right handed neutrino sector with the low energy neutrino data. In
the light of current neutrino oscillation data we studied the bound on the mass
scale ($M_1$) of lightest right handed neutrino ($N_1$) as well as their mass
hierarchy ($M_2/M_1$ and $M_3/M_1$) from the leptogenesis constraint which we
discussed in two different parts of the thesis. In part-I, we studied the
canonical leptogenesis in a {\it thermal} scenario and hence the bound on
$M_1$. It is shown that the mass scale of $N_1$ must satisfy the constraint
$M_1\geq 10^8$ GeV in order to produce the adequate lepton asymmetry. We then
led to propose a model where this bound can be relaxed to TeV scale. In
part-II, we studied the formation and evolution of topological defects which
are non-thermal objects and are expected to be formed during the early Universe
phase transitions. In particular, we considered $B-L$ cosmic strings and their
effect on leptogenesis and hence the bound on the mass scale of $N_1$. It is
shown that for the $B-L$ symmetry breaking scale $\eta_{B-L}>10^{11}$GeV, in
certain parameter space, the cosmic strings make a more dominant contribution
than thermal leptogenesis.

Title: Inflation from Superstring/M-Theory Compactification with Higher Order
Corrections II -- Case of Quartic Weyl Terms --
Authors:
Kenta Akune,
Kei-ichi Maeda,
Nobuyoshi Ohta
Comments: 40 pages, 11 figures
We present a detailed study of inflationary solutions in M-theory with higher
order quantum corrections. We first exhaust all exact and asymptotic solutions
of exponential and power-law expansions in this theory with quartic curvature
corrections, and then perform a linear perturbation analysis around fixed
points for the exact solutions in order to see which solutions are more generic
and give interesting cosmological models. We find an interesting solution in
which the external space expands exponentially and the internal space is static
both in the original and Einstein frames. This may be regarded as moduli
stabilization by higher order corrections. Furthermore, we perform a numerical
calculation around this solution and find numerical solutions which give enough
e-foldings. We also briefly summarize similar solutions in type II
superstrings.

Title: Leading Log Solution for Inflationary Yukawa
Authors:
Shun-Pei Miao,
R. P. Woodard (University of Florida)
Comments: 35 pages, LaTeX 2epsilon, 4 figures (using axodraw)
We generalize Starobinskii's stochastic technique to the theory of a
massless, minimally coupled scalar interacting with a massless fermion in a
locally de Sitter geometry. The scalar is an ``active'' field that can engender
infrared logarithms. The fermion is a ``passive'' field that cannot cause
infrared logarithms but which can carry them, and which can also induce new
interactions between the active fields. The procedure for dealing with passive
fields is to integrate them out, then stochastically simplify the resulting
effective action following Starobinski\u{\i}. Because Yukawa theory is
quadratic in the fermion this can be done explicitly using the classic solution
of Candelas and Raine. We check the resulting stochastic formulation against an
explicit two loop computation. We also derive a nonperturbative, leading log
result for the stress tensor. Because the scalar effective potential induced by
fermions is unbounded below, back-reaction from this model might dynamically
cancel an arbitrarily large cosmological constant.

Title: Unification of Dark Energy and Dark Matter
Authors:
Fuminobu Takahashi,
T. T. Yanagida
Comments: 10 pages, no figure, references and comments are added, version
accepted for publication by Physics Letters B
We propose a scenario in which dark energy and dark matter are described in a
unified manner. The ultralight pseudo-Nambu-Goldstone (pNG) boson, A, naturally
explains the observed magnitude of dark energy, while the bosonic supersymmetry
partner of the pNG boson, B, can be a dominant component of dark matter. The
decay of B into a pair of electron and positron may explain the 511 keV gamma
ray from the Galactic Center.

Title: Hidden supersymmetry of domain walls and cosmologies
Authors:
Kostas Skenderis,
Paul K. Townsend
Comments: 4 pages
We show that all domain-wall solutions of gravity coupled to scalar fields
for which the worldvolume geometry is Minkowski or anti-de Sitter admit Killing
spinors, and satisfy corresponding first-order equations involving a
superpotential determined by the solution. By analytic continuation, all flat
or closed FLRW cosmologies are shown to satisfy similar first-order equations
arising from the existence of ``pseudo-Killing'' spinors.

Title: Attractor solutions for general hessence dark energy
Authors:
M. Alimohammadi,
H. Mohseni Sadjadi
Comments: 11 pages, LaTeX
As a candidate for the dark energy, the hessence model has been recently
introduced. We discuss the critical points of this model in general case, that
is for arbitrary hessence potential and arbitrary hessence-background matter
interaction. It is shown that in all models, there always exist some stable
late-time attractors. It is shown that our general results coincide with those
solutions obtained earlier for special cases, but some of them are new. These
new solutions have two unique characteristics. First the hessence field has
finite value in these solutions and second, their stabilities depend on the
second derivative of the hessence potential.

Title: Semirelativistic stability of boson stars and tightened bounds on their
critical mass
Authors:
Richard L. Hall,

Comments: 8 pages
Subj-class: High Energy Physics - Theory; Mathematical Physics
We study a system of self-gravitating identical bosons by means of a
semirelativistic Hamiltonian comprising the relativistic kinetic energies of
the involved particles and added (instantaneous) Newtonian gravitational pair
interaction potentials. With the help of an improved lower bound to the bottom
of the spectrum of this Hamiltonian, we are able to enlarge the known region
for relativistic stability of boson stars against gravitational collapse and to
sharpen the predictions for their maximum stable mass.

Title: Cosmic Strings

Cosmic strings, a hot subject in the 1980's and early 1990's, lost its appeal
when it was found that it leads to inconsistencies in the power spectrum of the
measured cosmic microwave background temperature anisotropies. However,
topological defects in general, and cosmic strings in particular, are deeply
rooted in the framework of grand unified theories. Indeed, it was shown that
cosmic strings are expected to be generically formed within supersymmetric
grand unified theories. This theoretical support gave a new boost to the field
of cosmic strings, a boost which has been recently enhanced when it was shown
that cosmic superstrings (fundamental or one-dimensional Dirichlet branes) can
play the role of cosmic strings, in the framework of braneworld cosmologies.
To build a cosmological scenario we employ high energy physics; inflation and
cosmic strings then naturally appear. Confronting the predictions of the
cosmological scenario against current astrophysical/cosmological data we impose
constraints on its free parameters, obtaining information about the high energy
physics we employed.
This is a beautiful example of the rich and fruitful interplay between
cosmology and high energy physics.

Title: Gravitating semirelativistic N-boson systems
Authors:

Comments: 7 pages, 2 figures
Subj-class: Mathematical Physics
MSC-class: 81Q05; 81V70; 81V17
Analytic energy bounds for N-boson systems governed by semirelativistic
Hamiltonians of the form H=\sum_{i=1}^N(p_i^2 + m^2)^{1/2} - sum_{1=i<j}^N
v/r_{ij}, with v>0, are derived by use of Jacobi relative coordinates. For
gravity v=c/N, these bounds are substantially tighter than earlier bounds and
they are shown to coincide with known results in the nonrelativistic limit.

Title: Ricci Flow Gravity
Authors:
Wolfgang Graf
Comments: 15 pages. V2: improved presentation, in particular Jordan vs.
Brans-Dicke and on viability. Added section on physical interpretation
Subj-class: General Relativity and Quantum Cosmology; Differential Geometry
A theory of gravitation is proposed, modeled after the notion of a Ricci
flow. In addition to the metric an independent volume enters as a fundamental
geometric structure. Einstein gravity is included as a limiting case. Despite
being a scalar-tensor theory the coupling to matter is different from
Jordan-Brans-Dicke gravity. In particular there is no adjustable coupling
constant. For the solar system the effects of Ricci flow gravity cannot be
distinguished from Einstein gravity and therefore it passes all classical
tests. However for cosmology significant deviations from standard Einstein
cosmology will appear.

Title: Finite cosmology and a CMB cold spot
Authors:
R.J. Adler,
J.D. Bjorken,
J.M. Overduin
Comments: 20 pages, 12 figures
The standard cosmological model posits a spatially flat universe of infinite
extent. However, no observation, even in principle, could verify that the
matter extends to infinity. In this work we model the universe as a finite
spherical ball of dust and dark energy, and obtain a lower limit estimate of
its mass and present size: the mass is at least 5 x 10^23 solar masses and the
present radius is at least 50 Gly. If we are not too far from the dust-ball
edge we might expect to see a cold spot in the cosmic microwave background, and
there might be suppression of the low multipoles in the angular power spectrum.
Thus the model may be testable, at least in principle. We also obtain and
discuss the geometry exterior to the dust ball; it is Schwarzschild-de Sitter
with a naked singularity, and provides an interesting picture of cosmogenesis.
Finally we briefly sketch how radiation and inflation eras may be incorporated
into the model.

The impact of the leading quantum gravity effects on the dynamics of the
Hawking evaporation process of a black hole is investigated. Its spacetime
structure is described by a renormalization group improved Vaidya metric. Its
event horizon, apparent horizon, and timelike limit surface are obtained taking
the scale dependence of Newton's constant into account. The emergence of a
quantum ergosphere is discussed. The final state of the evaporation process is
a cold, Planck size remnant.

We studied electron amplification and light emission from avalanches in
oxygen-containing gas mixtures. The mixtures investigated in this work
included, among others, CO2 and N2O mixed with Triethylamine (TEA) or N2.
Double-Step Parallel Gap (DSPG) multipliers and THick Gas Electron Multipliers
(THGEM) were investigated. High light yields were measured from CO2+N2 and
CO2+TEA, though with different emission spectra. We observed the characteristic
wave-length emission of N2 and of TEA and used a polymer wave-length shifter to
convert TEA UV-light into the visible spectrum. The results of these
measurements indicate the applicability of optical recording of ionizing tracks
in a TPC target-detector designed to study the cross section of the 16O(g,a)12C
reaction, a central problem in nuclear astrophysics.
