Shock Acceleration and Gamma-Ray Emitting Supernova Remnants

Matthew G. Baring, Donald C. Ellison, Stephen P. Reynolds +2

Diffusive shock acceleration in the environs of a remnant's expanding shell is a popular candidate for the origin of SNR gamma-rays. In this paper, results from our study of non-li…

Mixing angles and electromagnetic properties of ground state pseudoscalar and vector meson nonets in the light-cone quark model

Ho-Meoyng Choi, Chueng-Ryong Ji

Both the mass spectra and the wave functions of the light pseudoscalar () and vector() mesons are analyzed within the framework of the light-cone constituent…

Measurements at low energies of the polarization-transfer coefficient Kyy' for the reaction 3H(p,n)3He at 0 degrees

W. S. Wilburn, C. R. Gould, G. M. Hale +4

Measurements of the transverse polarization coefficient Kyy' for the reaction 3H(p,n)3He are reported for outgoing neutron energies of 1.94, 5.21, and 5.81 MeV. This reaction is im…

Coupled Channel Analysis of S-Wave Pion-Pion and Kaon-Kaon Photoproduction

Chueng-Ryong Ji, Robert Kaminski, Leonard Lesniak +2

We present a coupled channel partial wave analysis of nondiffractive S-wave pi+ pi- and K+ K- photoproduction focusing on the KK threshold. Final state interactions are included. W…

Investigation of Neutrino-Driven Convection and the Core Collapse Supernova Mechanism Using Multigroup Neutrino Transport

A. Mezzacappa, A. C. Calder, S. W. Bruenn +4

We investigate neutrino-driven convection in core collapse supernovae and its ramifications for the explosion mechanism, for a 15 solar mass model. Our two-dimensional simulation b…

The Interplay Between Protoneutron Star Convection and Neutrino Transport in Core Collapse Supernovae

A. Mezzacappa, A. C. Calder, S. W. Bruenn +4

We couple two-dimensional hydrodynamics to realistic one-dimensional multigroup flux-limited diffusion neutrino transport to investigate protoneutron star convection in core collap…

Consistent Analysis of O(α_s) Corrections to Pion Elastic Form Factor

Adam Szczepaniak, Anatoly Radyushkin, Chueng-Ryong Ji

We examine the role of O(α_s) perturbative corrections to the pion elastic form factor F_π(Q^2). We express the quark current three-point function in terms of light cone variables…

Black holes with short hair

David Brown, Viqar Husain

We present spherically symmetric black hole solutions for Einstein gravity coupled to anisotropic matter. We show that these black holes have arbitrarily short hair, and argue for…

Crystals for Demazure Modules of Classical Affine Lie Algebras

A. Kuniba, K. C. Misra, M. Okado +2

We study, in the path realization, crystals for Demazure modules of affine Lie algebras of types $A^{(1)}_n,B^{(1)}_n,C^{(1)}_n,D^{(1)}_n, A^{(2)}_{2n-1},A^{(2)}_{2n}, and D^{(2)}_…

Characters of Demazure modules and solvable lattice models

A. Kuniba, K. C. Misra, M. Okado +2

We study the path realization of Demazure crystals related to solvable lattice models in statistical mechanics. Various characters are represented in a unified way as the sums over…

Hybrids and Quark Confinement

E. S. Swanson

It has become traditional to assume that the Dirac structure of the phenomenological quark confinement potential is scalar scalar. We use the heavy quark expansion of the…

Galactic Cosmic Rays from Supernova Remnants: II Shock Acceleration of Gas and Dust

Donald C. Ellison, L. O'C. Drury, Jean-Paul Meyer

This is the second paper (the first was astro-ph/9704267) of a series analysing the Galactic Cosmic Ray (GCR) composition and origin. In this we present a quantitative model of GCR…

Hybrid Decays

Eric S. Swanson, Adam P. Szczepaniak

The heavy quark expansion of Quantum Chromodynamics and the strong coupling flux tube picture of nonperturbative glue are employed to develop the phenomenology of hybrid meson deca…

Galactic Cosmic Rays from Supernova Remnants (I) - a Cosmic Ray Composition controlled by Volatility and Mass-to-Charge Ratio

Jean-Paul Meyer, L. O'C. Drury, Donald C. Ellison

This is the first of a series of papers analysing the Galactic Cosmic Ray composition and origin. We show that the Galactic Cosmic Ray source (GCRS) composition is best described i…

Boundary States and Black Hole Entropy

David Brown

Black hole entropy is derived from a sum over boundary states. The boundary states are labeled by energy and momentum surface densities, and parametrized by the boundary metric. Th…

Duality Invariance of Black Hole Creation Rates

David Brown

Pair creation of electrically charged black holes and its dual process, pair creation of magnetically charged black holes, are considered. It is shown that the creation rates are e…
