Remarks on Tachyon Driven Cosmology
Ashoke Sen
We begin by reviewing the results on the decay of unstable D-branes in type II string theory, and the open-closed string duality proposal that arises from these studies. We then ap…
Bose-Einstein correlations in one and two dimensions in deep inelastic scattering
ZEUS Collaboration
Bose-Einstein correlations in one and two dimensions have been studied in deep inelastic EP scattering events measured with the ZEUS detector at HERA using an integrated luminosity…
Measurements of Branching Fractions and CP-Violating Asymmetries in B Meson Decays to Charmless Two-Body States Containing a K0
B. Aubert, BABAR Collaboration
We present measurements of branching fractions and \CP-violating asymmetries in decays of mesons to two-body final states containing a \Kz. The results are based on a data samp…
Isolated tau leptons in events with large missing transverse momentum at HERA
ZEUS collaboration
A search for events containing isolated tau leptons and large missing transverse momentum, not originating from the tau decay, has been performed with the ZEUS detector at the elec…
ACS Observations of a Strongly Lensed Arc in a Field Elliptical

We present a measurement of the branching fraction for the decay B- --> D0 K*- using a sample of approximately 86 million BBbar pairs collected by the BaBar detector from e+e- coll…
On the Surface Heating of Synchronously-Spinning Short-Period Jovian Planets
Andreas Burkert, Douglas Lin, Peter Bodenheimer +2
We consider the atmospheric flow on short-period extra-solar planets through two-dimensional numerical simulations of hydrodynamics with radiation transfer. One side is always expo…
On the C and N Abundances of 47 Tucanae Main Sequence Stars
Michael M. Briley, Daniel Harbeck, Graeme H. Smith +1
We report the results of an analysis of CN and CH band strengths among a large sample of 47 Tucanae main-sequence and turn-off stars presented earlier by Harbeck et al. The resulti…
Keck Spectroscopy and Imaging of Globular Clusters in the Lenticular Galaxy NGC 524
Michael A. Beasley, Duncan A. Forbes, Jean P. Brodie +1
We have obtained Keck LRIS imaging and spectra for 29 globular clusters associated with the lenticular galaxy NGC 524. Using the empirical calibration of Brodie & Huchra we find th…
Aging Dynamics of the Heisenberg Spin Glass
L. Berthier, A. P. Young
We numerically study the non-equilibrium dynamics of the three dimensional Heisenberg Edwards-Anderson spin glass following a sudden quench to its low temperature phase. The subseq…
The detailed Fundamental Plane of two high redshift clusters: MS 2053-04 at z=0.58 and MS 1054-03 at z=0.83
Stijn Wuyts, Pieter G. van Dokkum, Daniel D. Kelson +2
We study the fundamental plane relation in high redshift clusters using a sample of 26 galaxies in MS 2053-04 (z=0.583) and 22 galaxies in MS 1054-03 (z=0.83). The zeropoint and sc…
Star Formation and Feedback in Dwarf Galaxies
Shawfeng Dong, D. N. C. Lin, S. D. Murray
We examine the star formation history and stellar feedback effects of dwarf galaxies under the influence of extragalactic ultraviolet radiation. We consider the dynamical evolution…
A comprehensive set of elemental abundances in damped Ly-alpha systems: revealing the nature of these high-redshift galaxies
M. Dessauges-Zavadsky, F. Calura, J. X. Prochaska +2
By combining our UVES-VLT spectra of a sample of four damped Ly-alpha systems (DLAs) toward the quasars Q0100+13, Q1331+17, Q2231-00 and Q2343+12 with the existing HIRES-Keck spect…
Towards a Deterministic Model of Planetary Formation I: a Desert in the Mass and Semi Major Axis Distributions of Extra Solar Planets
S. Ida, D. N. C. Lin
We examine the accretion of cores of giant planets from planetesimals, gas accretion onto the cores, and their orbital migration. We adopt a working model for nascent protostellar…
Measurement of Branching Fractions and Charge Asymmetries in B+ --> rho+pi0 and B+ -->rho0pi+ Decays, and Search for B0 --> rho0pi0
B. Aubert
We present measurements of branching fractions and charge asymmetries in -meson decays to , and . The data sample comprises $Υ(4S)…
Non-contractible periodic orbits of Hamiltonian flows on twisted cotangent bundles
Cesar J. Niche
For many classes of symplectic manifolds, the Hamiltonian flow of a function with sufficiently large variation must have a fast periodic orbit. This principle is the base of the no…
Lepton-flavor mixing and decays
Yuval Grossman, Gino Isidori, Hitoshi Murayama
The impact of possible sources of lepton-flavor mixing on decays is analysed. At the one-loop level lepton-flavor mixing originated from non-diagonal lepton mass ma…
