Radiative B Decays: Standard Candles of Flavor Physics
Matthias Neubert
Rare radiative decays based on b->s+gamma transitions are among the most prominent examples of flavor-changing neutral current processes. They benefit from good theoretical control…
Measurement of Lepton Momentum Moments in the Decay bar{B} \to X \ell \barν and Determination of Heavy Quark Expansion Parameters and |V_cb|
A. H. Mahmood
We measure the primary lepton momentum spectrum in B-bar to X l nu decays, for p_l > 1.5 GeV/c in the B rest frame. From this, we calculate various moments of the spectrum. In part…
Radio-selected Galaxies in Very Rich Clusters at z < 0.25: I. Multi-wavelength Observations and Data Reduction Techniques
G. E. Morrison, F. N. Owen, M. J. Ledlow +4
Radio observations were used to detect the `active' galaxy population within rich clusters of galaxies in a non-biased manner that is not plagued by dust extinction or the K-correc…
Ab initio and finite-temperature molecular dynamics studies of lattice resistance in tantalum
D. E. Segall, Alejandro Strachan, Sohrab Ismail-Beigi +2
This manuscript explores the apparent discrepancy between experimental data and theoretical calculations of the lattice resistance of bcc tantalum. We present the first results for…
The Evolution Of LMC X-4 Flares: Evidence For Super-Eddington Radiation Oozing Through Inhomogeneous Polar Cap Accretion Flows ?
Dae-Sik Moon, Stephen S. Eikenberry, Ira M. Wasserman
We present the results of two extensive Rossi X-ray Timing Explorer observations of large X-ray flaring episodes from the high-mass X-ray binary pulsar LMC X-4. Light curves during…
Core-Collapse Supernovae and Neutron Star Kicks
Dong Lai
Recent observations have revealed many new puzzles related to core-collapse supernovae, including the formation of magnetars and black holes and their possible GRB connections. We…
ISOCAM view of the starburst galaxies M82, NGC253, and NGC1808
N. M. Foerster Schreiber, M. Sauvage, V. Charmandaris +4
We present results of mid-infrared 5.0-16.5 micron spectrophotometric imaging of the starburst galaxies M82, NGC253, and NGC1808 from the ISOCAM instrument on board the Infrared Sp…
Atmospheres of Magnetized Neutron Stars: Vacuum Polarization and Partially Ionized Models
Wynn C. G. Ho, Dong Lai, Alexander Y. Potekhin +1
We construct hydrogen atmosphere models for magnetized neutron stars in radiative equilibrium with surface fields B=10^12-5x10^14 G and effective temperatures T_eff a few x 10^5-10…
Comment on ``Dynamical Foundations of Nonextensive Statistical Mechanics"
Alice M. Crawford, Nicolas Mordant, Andy M. Reynolds +1
In a recent letter, Christian Beck described a theoretical link between a family of stochastic differential equations and the probability density functions (PDF) derived from the f…
Finiteness properties of soluble arithmetic groups over global function fields
Kai-Uwe Bux
Let G be a Chevalley group scheme and B<=G a Borel subgroup scheme, both defined over Z. Let K be a global function field, S be a finite non-empty set of places over K, and O_S be…
Compact group actions that raise dimension to infinity
A. N. Dranishnikov, J. E. West
THEOREM. For every prime and each , there is an action of on a two-dimensional compact metric space with -dimensional…
Generalized Lame operators
Oleg Chalykh, Pavel Etingof, Alexei Oblomkov
We introduce a class of multidimensional Schrödinger operators with elliptic potential which generalize the classical Lamé operator to higher dimensions. One natural example is the…
An Improved Brane Anti-Brane Action from Boundary Superstring Field Theory and Multi-Vortex Solutions
Nicholas T. Jones, S. -H. Henry Tye
We present an improved effective action for the D-brane-anti-D-brane system obtained from boundary superstring field theory. Although the action looks highly non-trivial, it has si…
Exactly solvable model of three interacting particles in an external magnetic field
E. P. Nakhmedov, K. Morawetz, M. Ameduri +2
The quantum mechanical problem of three identical particles, moving in a plane and interacting pairwise via a spring potential, is solved exactly in the presence of a magnetic fiel…
Revised term of lepton from the Feynman diagrams containing an internal light-by-light scattering subdiagram
T. Kinoshita, M. Nio
The contribution to the lepton from a gauge-invariant set of 18 Feynman diagrams containing a light-by-light scattering subdiagram internally has been reevaluated by a…
Azimuthal and Kinematic Segregation of Neutral and Molecular Gas in Arp 118: The Yin-Yang Galaxy NGC 1144
P. N. Appleton, V. Charmandaris, Yu Gao +2
We present new high-resolution HI observations of the disk of the collisional infrared luminous (L L$_{\sun}$) galaxy NGC 1144, which reveal an apparent…
Vortex dynamics in the nonlinear Schrodinger equation
Michael J. Quist
The dynamics of a two-dimensional vortex are analyzed within the framework of the nonlinear Schrodinger equation. Both a bare vortex and a vortex with an external mass trapped in a…
My Life with Fisher
N. David Mermin
This is based on the after-dinner talk given at the 70th Birthday Conference for Michael E. Fisher at Rutgers in December, 2001. It is longer than the talk, incorporating additiona…
Thermally Enhanced Neutralization in Hyperthermal Energy Ion Scattering
C. E. Sosolik, J. R. Hampton, A. C. Lavery +2
Neutralization probabilities are presented for hyperthermal energy Na+ ions scattered from a Cu(001) crystal as a function of surface temperature and scattered velocity. A large en…
Magnetically Driven Warping and Precession of Accretion Disks: Implications for "Exotic" Stellar Variabilities
Dong Lai
The inner region of the accretion disk around a magnetized star is subjected to magnetic torques that induce warping and precession of the disk. These torques arise from interactio…
