Quantum Brownian Motion in a Bath of Parametric Oscillators: A model for system-field interactions
B. L. Hu, Andrew Matacz
The quantum Brownian motion paradigm provides a unified framework where one can see the interconnection of some basic quantum statistical processes like decoherence, dissipation, p…
Quantum Noise in Gravitation and Cosmology
Bei-lok Hu, Andrew Matacz
We begin by enumerating the many processes in gravitation and cosmology where quantum noise and fluctuations play an active role such as particle creation, galaxy formation and ent…
Deep Inelastic Scattering from off-Shell Nucleons
W. Melnitchouk, A. W. Schreiber, A. W. Thomas
We derive the general structure of the hadronic tensor required to describe deep-inelastic scattering from an off-shell nucleon within a covariant formalism. Of the large number of…
Medium Modification to the -Meson Mass in the Walecka Model
H. -C. Jean, J. Piekarewicz, A. G. Williams
We calculate the effective mass of the meson in nuclear matter in a relativistic random-phase approximation to the Walecka model. The dressing of the meson propagator is driven…
The Spin Structure of the Nucleon
S. D. Bass, A. W. Thomas
We provide an introduction to the ideas of spin-dependent deep-inelastic scattering. Recent experimental results are summarised and possible explanations related to the axial anoma…
Nuclear Shadowing at Small x and Q^2
W. Melnitchouk, A. W. Thomas
Shadowing corrections to structure functions of heavy nuclei are calculated at very low values of Bjorken- and at values of the momentum transfer relevant to recent experiments.…
Pion Form Factors at Intermediate Momentum Transfer in a Covariant Approach
A. Szczepaniak, A. G. Williams
We study the pion electromagnetic and transition form factors at intermediate momentum transfer. We calculate soft, nonperturbative corrections to the leading per…
Dynamical chiral symmetry breaking and confinement with an infrared-vanishing gluon propagator?
Frederick T. Hawes, Craig D. Roberts, Anthony G. Williams
We study a model Dyson-Schwinger equation for the quark propagator closed using an {\it Ansatz} for the gluon propagator of the form \mbox{} and two…
Ultra--Planck Scattering in D=3 Gravity Theories
S. Deser, J. McCarthy, Alan R. Steif
We obtain the high energy, small angle, 2-particle gravitational scattering amplitudes in topologically massive gravity (TMG) and its two non-dynamical constituents, Einstein and C…
Charge-Symmetry Breaking, Rho-Omega Mixing and the Quark Propagator
G. Krein, A. W. Thomas, A. G. Williams
The momentum-dependence of the - mixing contribution to charge-symmetry breaking (CSB) in the nucleon-nucleon interaction is compared in a variety of models. We focus in pa…
Phase-Space Decoherence: a comparison between Consistent Histories and Environment Induced Superselection
J. Twamley
We examine the decoherence properties of a quantum open system as modeled by a quantum optical system in the Markov regime. We look for decoherence in both the Environment Induced…
Mapping the x dependence of the axial anomaly in polarised deep inelastic scattering
S. D. Bass, A. W. Thomas
We discuss the role of the U(1) axial anomaly in the spin structure functions of the nucleon, with particular emphasis on how one might determine its x dependence in present and fu…
Decoherence Functional and Inhomogeneities in the Early Universe
R. Laflamme, A. Matacz
We investigate the quantum to classical transition of small inhomogeneous fluctuations in the early Universe using the decoherence functional of Gell-Mann and Hartle. We study two…
Semi-infinite cohomology of W-algebras
P. Bouwknegt, J. McCarthy, K. Pilch
We generalize some of the standard homological techniques to $\cW$-algebras, and compute the semi-infinite cohomology of the $\cW_3$ algebra on a variety of modules. These computat…
The quantum behavior of general time dependent quadratic systems linearly coupled to a bath
J. Twamley
In this paper we solve for the quantum propagator of a general time dependent system quadratic in both position and momentum, linearly coupled to an infinite bath of harmonic oscil…
Role of Vector Mesons in High-Q^2 Lepton-Nucleon Scattering
W. Melnitchouk, A. W. Thomas
The possible role played by vector mesons in inclusive deep inelastic lepton-nucleon scattering is investigated. In the context of the convolution model, we calculate self-consiste…
Shadowing in Deuterium
W. Melnitchouk, A. W. Thomas
We calculate nuclear shadowing in lepton-deuteron deep inelastic scattering, which arises from the double scattering of the virtual photon from both nucleons in the deuteron. The t…
