Extraction of bounds on time-reversal non-invariance from neutron reactions
E. D. Davis, C. R. Gould
Ratios involving on-resonance measurements of the three-fold and five-fold correlation cross sections for which the dependence on some of the unknown spectroscopic data is eliminat…
-Wedge Modules for Quantized Enveloping Algebras of Classical Type
Naihuan Jing, Kailash C. Misra, Masato Okado
We use the fusion construction in the twisted quantum affine algebras to obtain a unified method to deform the wedge product for classical Lie algebras. As a byproduct we uniformly…
Renormalized Effective QCD Hamiltonian: Gluonic Sector
D. G. Robertson, E. S. Swanson, A. P. Szczepaniak +2
Extending previous QCD Hamiltonian studies, we present a new renormalization procedure which generates an effective Hamiltonian for the gluon sector. The formulation is in the Coul…
New HST Observations of High Velocity Lyman Alpha and Balmer Alpha in SNR 1987A
Eli Michael, Richard McCray, C. S. J. Pun +12
We describe and model high velocity (~15,000 km/s) Lyman alpha and Balmer alpha emission from supernova remnant 1987A seen in September and October 1997 with the Space Telescope Im…
Radio to Gamma-Ray Emission from Shell-type Supernova Remnants: Predictions from Non-linear Shock Acceleration Models
Matthew G. Baring, Donald C. Ellison, Stephen P. Reynolds +2
Supernova remnants (SNRs) are widely believed to be the principal source of galactic cosmic rays. Such energetic particles can produce gamma-rays and lower energy photons via inter…
Geodesic Deviation in Regge Calculus
Sukanya Chakrabarti, Adrian P. Gentle, Arkady Kheyfets +1
Geodesic deviation is the most basic manifestation of the influence of gravitational fields on matter. We investigate geodesic deviation within the framework of Regge calculus, and…
Gorensteinness of invariant subrings of quantum algebras
Naihuan Jing, James J. Zhang
We prove Auslander-Gorenstein and $\GKdim$-Macaulay properties for certain invariant subrings of some quantum algebras, the Weyl algebras, and the universal enveloping algebras of…
Conformal ``thin sandwich'' data for the initial-value problem of general relativity
James W. York
The initial-value problem is posed by giving a conformal three-metric on each of two nearby spacelike hypersurfaces, their proper-time separation up to a multiplier to be determine…
Canonical Quasilocal Energy and Small Spheres
J. D. Brown, S. R. Lau, J. W. York
Consider the definition E of quasilocal energy stemming from the Hamilton-Jacobi method as applied to the canonical form of the gravitational action. We examine E in the standard "…
Renormalized Effective Hamiltonian Approach to QCD
D. G. Robertson, E. S. Swanson, A. P. Szczepaniak +2
Continuing our previous QCD Hamiltonian studies in the gluonic and quark sectors, we describe a new renormalization procedure which generates an effective Hamiltonian. The formulat…
Direct Acceleration of Pickup Ions at the Solar Wind Termination Shock: the Production of Anomalous Cosmic Rays
Donald C. Ellison, Frank C. Jones, Matthew G. Baring
We have modeled the injection and acceleration of pickup ions at the solar wind termination shock and investigated the parameters needed to produce the observed Anomalous Cosmic Ra…
The Rotation Average in Lightcone Time-Ordered Perturbation Theory
Chueng-Ryong Ji, Gwang-Ho Kim, Dong-Pil Min
We present a rotation average of the two-body scattering amplitude in the lightcone time()-ordered perturbation theory. Using a rotation average procedure, we show that the cont…
Deutsch-Jozsa algorithm as a test of quantum computation
David Collins, K. W. Kim, W. C. Holton
A redundancy in the existing Deutsch-Jozsa quantum algorithm is removed and a refined algorithm, which reduces the size of the register and simplifies the function evaluation, is p…
Kaon electroweak form factors in the light-front quark model
Ho-Meoyng Choi, Chueng-Ryong Ji
We investigate the form factors and decay rates for the semileptonic decays of the kaon( using the light-front quark model. The form factors are calculate…
Canonical Basis and Macdonald Polynomials
Jonathan Beck, Igor Frenkel, Naihuan Jing
In the basic representation of realized via the algebra of symmetric functions we compare the canonical basis with the basis of Macdonald polynomials with $q=t^2…
Quantum Z-algebras and representations of quantum affine algebras
Naihuan Jing
Generalizing our earlier work, we introduce the homogeneous quantum -algebras for all quantum affine algebras $\alg$ of type one. With the new algebras we unite previously scatt…
Nonvanishing zero modes in the light-front current
Ho-Meoyng Choi, Chueng-Ryong Ji
We find that the zero mode( mode of a continuum theory) contribution is crucial to obtain the correct values of the light-front current in the Drell-Yan()…
Heavy Hybrids with Constituent Gluons
E. S. Swanson, A. P. Szczepaniak
Hybrid meson energies are calculated in the static quark limit with the Dynamical Quark Model (DQM). In the DQM, transverse gluons are represented as effective constituents with a…
Quantum Kac-Moody Algebras and Vertex Representations
Naihuan Jing
We introduce an affinization of the quantum Kac-Moody algebra associated to a symmetric generalized Cartan matrix. Based on the affinization, we construct a representation of the q…
Level One Representations of Quantum Affine Algebras
Naihuan Jing, Yoshitaka Koyama, Kailash Misra
We give explicit constructions of quantum symplectic affine algebras at level 1 using vertex operators.
G359.87+0.18: A Young SNR Candidate Near the Galactic Center?
F. Yusef-Zadeh, W. D. Cotton, S. P. Reynolds
Sub-arcsecond radio continuum observations of the Galactic center region at 6 and 2cm reveal a 0.5 diameter source with a shell-like morphology. This source is…
