BV-Structure of the Cohomology of Nilpotent Subalgebras and the Geometry of (W-) Strings
Peter Bouwknegt, Jim Mccarthy, Krzysztof Pilch
Given a simple, simply laced, complex Lie algebra $\bfg$ corresponding to the Lie group , let $\bfnp$ be the subalgebra generated by the positive roots. In this paper we constru…
Higher bundle gerbes and cohomology classes in gauge theories
A. L. Carey, M. K. Murray, B. L. Wang
The notion of a higher bundle gerbe is introduced to give a geometric realization of the higher degree integral cohomology of certain manifolds. We consider examples using the infi…
Index Theory, Gerbes, and Hamiltonian Quantization
Alan Carey, Jouko Mickelsson, Michael Murray
We give an Atiyah-Patodi-Singer index theory construction of the bundle of fermionic Fock spaces parametrized by vector potentials in odd space dimensions and prove that this leads…
The Role of Strange and Charm Quarks in the Nucleon Spin Structure Function
F. M. Steffens, A. W. Thomas
We perform an analysis of the relation between the factorization scale and the masses of the quarks in the calculation of the hard gluon coefficient in polarized deep inelastic sca…
Introduction to light forces, atom cooling, and atom trapping
Craig Savage
This paper introduces and reviews light forces, atom cooling and atom trapping. The emphasis is on the physics of the basic processes. In discussing conservative forces the semi-cl…
Chiral Symmetry Breaking in Strongly Coupled Quenched QED Using the Dyson-Schwinger Equation Formalism
A. G. Williams, F. T. Hawes
We study chiral symmetry breaking in quenched strong-coupling QED in arbitrary covariant gauge within the Dyson-Schwinger equation formalism. A recently developed numerical ren…
Vector Meson Mixing and Charge Symmetry Violation
H. B. O'Connell, A. G. Williams, M. Bracco +1
We discuss the consistency of the traditional vector meson dominance (VMD) model for photons coupling to matter, with the vanishing of vector meson-meson and meson-photon mixing se…
The W_3 algebra: modules, semi-infinite cohomology and BV-algebras
Peter Bouwknegt, Jim McCarthy, Krzysztof Pilch
The noncritical string is a model of gravity coupled to two free scalar fields. In this paper we discuss its BRST quantization in direct analogy with that of the…
A Study of Structure Functions for the Bag Beyond Leading Order
F. M. Steffens, A. W. Thomas
There has recently been surprising progress in understanding the spin and flavor dependence of deep inelastic structure functions in terms of the same physics needed in the simple…
The role of nucleon structure in finite nuclei
P. A. M. Guichon, K. Saito, E. Rodionov +1
The quark-meson coupling model, based on a mean field description of non-overlapping nucleon bags bound by the self-consistent exchange of , and mesons, is extended to i…
production as a probe of charge symmetry violations and nuclear corrections in parton distributions
G. Piller, A. W. Thomas
We investigate the sensitivity of production in proton-neutron and proton-deuteron collisions to charge symmetry violations in the parton distributions as well as to nuclear…
Mesonic Corrections to the Shape of Quark Distributions
F. M. Steffens, H. Holtmann, A. W. Thomas
We compute the full x - dependence of the proton and neutron spin structure functions in the MIT bag model, including the effect of gluon exchange and the meson cloud. Impressive a…
Symbolic Algebra and Renormalization of Gauge Theories
M. Rossi, A. P. Flitney
Symbolic algebra relevant to the renormalization of gauge theories can be efficiently performed by machine using modern packages. We devise a scheme for representing and manipulati…
Q**2 Dependence of Nuclear Shadowing
W. Melnitchouk, A. W. Thomas
We re-examine the predictions of a two-phase model of shadowing in nuclear deep-inelastic scattering in light of new NMC data on the x, A and Q**2 dependence of the ratios of struc…
Meson Cloud of the Nucleon in Polarized Semi-Inclusive Deep-Inelastic Scattering
W. Melnitchouk, A. W. Thomas
We investigate the possibility of identifying an explicit pionic component of the nucleon through measurements of polarized baryon fragments produced in deep-inelastic lep…
The gl(M|N) Super Yangian and Its Finite Dimensional Representations
R. B. Zhang
Methods are developed for systematically constructing the finite dimensional irreducible representations of the super Yangian Y(gl(M|N)) associated with the Lie superalgebra gl(M|N…
Effect of Nucleon Structure Variation in Super-allowed Fermi Beta-decay
Koichi Saito, Anthony W. Thomas
There is a well known anomaly between the value of the Fermi decay constant extracted from super-allowed Fermi beta-decay of nuclear isotriplets and that required by unitarity of t…
On the Uniqueness of the Twisted Representation in the Z_2 Orbifold Construction of a Conformal Field Theory from a Lattice
P. S. Montague
Following on from recent work describing the representation content of a meromorphic bosonic conformal field theory in terms of a certain state inside the theory corresponding to a…
Propagation of Ultra High Energy Protons over Cosmological Distances and Implications for Topological Defect Models
R. J. Protheroe, P. A. Johnson
We describe the results of a hybrid matrix--Monte Carlo calculation of cascading of UHE cosmic rays and -rays through the cosmic background radiation fields over cosmological di…
Composite nucleons in scalar and vector mean-fields
Koichi Saito, Anthony W. Thomas
We emphasize that the composite structure of the nucleon may play quite an important role in nuclear physics. It is shown that the momentum-dependent repulsive force of second orde…
Introduction to Quantum Field Theory
R. J. Crewther
Even the uninitiated will know that Quantum Field Theory cannot be introduced systematically in just four lectures. I try to give a reasonably connected outline of part of it, from…
SOLVING THE BETHE--SALPETER EQUATION IN MINKOWSKI SPACE: SCALAR THEORIES
Kensuke Kusaka, Anthony G. Williams
The Bethe-Salpeter (BS) equation for scalar-scalar bound states in scalar theories without derivative coupling is formulated and solved in Minkowski space. This is achieved using t…
Phenomenology of Nuclear Shadowing in Deep-Inelastic Scattering
G. Piller, W. Ratzka, W. Weise
We investigate shadowing effects in deep-inelastic scattering from nuclei at small values of the Bjorken variable. Unifying aspects of generalized vector meson dominance an…
Role of correlated two-pion exchange in scattering
M. Hoffmann, J. W. Durso, K. Holinde +2
A dynamical model for S-- and P--wave correlated (and ) exchange between a kaon and a nucleon is presented, starting from corresponding $N \bar N \rightarrow K \bar…
