A clue to the mechanism of production in -reactions
A. Sibirtsev, K. Tsushima, A. W. Thomas
We analyse the total cross section data which were recently measured by the COSY-11 collaboration at an energy 2~MeV above the reaction threshold. Our analysis sug…
New results in vector meson dominance and rho meson physics
A. G. Williams
Recent results by Benayoun et al. comparing the predictions of a range of existing models based on the Vector Meson Dominance hypothesis are summarized and discussed. These are com…
Lattice Calculation of the Strangeness Magnetic Moment of the Nucleon
S. J. Dong, K. F. Liu, A. G. Williams
We report on a lattice QCD calculation of the strangeness magnetic moment of the nucleon. Our result is . The sea contributions from the u and d quarks…
--Dependence of the Gerasimov-Drell-Hearn Sum Rule
W. X. Ma, D. H. Lu, A. W. Thomas +1
We test the Gerasimov-Drell-Hearn (GDH) sum rule numerically by calculating the total photon absorption cross sections and on the nucleon via photon excitation…
Constrained Dynamics for Quantum Mechanics I. Restricting a Particle to a Surface
Hendrik Grundling, C. A. Hurst
We analyze constrained quantum systems where the dynamics do not preserve the constraints. This is done in particular for the restriction of a quantum particle in Euclidean n-space…
In-medium kaon and antikaon properties in the quark-meson coupling model
K. Tsushima, K. Saito, A. W. Thomas +1
The properties of the kaon, , and antikaon, $\kbar$, in nuclear medium are studied in the quark-meson coupling (QMC) model. Employing a constituent quark-antiquark (MIT bag mode…
Medium dependence of the bag constant in the quark-meson coupling model
D. H. Lu, K. Tsushima, A. W. Thomas +2
Possible variations of the quark-meson coupling (QMC) model are examined in which the bag constant decreases in the nuclear medium. The reduction is supposed to depend on either th…
Lambda(1405) as a multiquark state
Seungho Choe
In the QCD sum rule approach we predict the (1405) mass by choosing the multiquark interpolating field. It is found that the mass is about 1.419 GeV from s…
Analytic structure of scalar composites in the symmetric phase of the gauged Nambu-Jona-Lasinio model
V. P. Gusynin, M. Reenders
The gauged Nambu-Jona-Lasinio model in the quenched-ladder approximation has non-trivial dynamics near a critical scaling region (critical curve) separating a chiral symmetric and…
Light Hadron Spectroscopy on Coarse Lattices with O(a^2) Mean-Field Improved Actions
Frank X. Lee, Derek B. Leinweber
The masses and dispersions of light hadrons are calculated in lattice QCD using an O(a^2) tadpole-improved gluon action and an O(a^2) tadpole-improved next-nearest-neighbor fermion…
Bundle Gerbes Applied to Quantum Field Theory
Alan Carey, Jouko Mickelsson, Michael Murray
This paper reviews recent work on a new geometric object called a bundle gerbe and discusses some new examples arising in quantum field theory. One application is to an Atiyah-Pato…
Vector Coherent State Realization of Representations of the Affine Lie Algebra
R. B. Zhang
The method of vector coherent states is generalized to study representations of the affine Lie algebra . A large class of highest weight irreps is explicitly construct…
Deconfinement at finite chemical potential
A. Bender, G. I. Poulis, C. D. Roberts +2
In a confining, renormalisable, Dyson-Schwinger equation model of two-flavour QCD we explore the chemical-potential dependence of the dressed-quark propagator, which provides a mea…
Analytic and Asymptotic Methods for Nonlinear Singularity Analysis: a Review and Extensions of Tests for the Painlevé Property
Martin D. Kruskal, Nalini Joshi, Rod Halburd
The integrability (solvability via an associated single-valued linear problem) of a differential equation is closely related to the singularity structure of its solutions. In parti…
The Second Painlevé Equation in the Large-Parameter Limit I: Local Asymptotic Analysis
Nalini Joshi
In this paper, we find all possible asymptotic behaviours of the solutions of the second Painlevé equation as the parameter in the local region $x\llα…
Detection of Gamma Rays of Up to 50 TeV From the Crab Nebula
T. Tanimori, K. Sakurazawa, S. A. Dazeley +28
Gamma rays with energies greater than 7 TeV from the Crab pulsar/nebula have been observed at large zenith angles, using the Imaging Atmospheric Technique from Woomera, South Austr…
The deformed Virasoro algebra at roots of unity
P. Bouwknegt, K. Pilch
We discuss some aspects of the representation theory of the deformed Virasoro algebra $\virpq$. In particular, we give a proof of the formula for the Kac determinant and then deter…
Very high energy gamma rays from Markarian 501
R. J. Protheroe, C. L. Bhat, P. Fleury +3
During remarkable flaring activity in 1997 Markarian 501 was the brightest source in the sky at TeV energies, outshining the Crab Nebula by a factor of up to 10. Periods of flaring…
Induced Chern-Simons terms
Jim McCarthy, Andy Wilkins
We examine the claim that the effective action of four-dimensional SU(2)_L gauge theory at high and low temperature contains a three-dimensional Chern-Simons term with coefficient…
Variational treatment of quenched QED using the worldline technique
A. W. Schreiber, C. Alexandrou, R. Rosenfelder
There has been growing interest in studying the behaviour of QED in its strong coupling limit. The reason for this is not only that it serves as a simple prototype gauge theory for…

J. M. Figueroa-O'Farrill, A. Imaanpur, J. McCarthy
We consider the dimensional reduction of supersymmetric Yang-Mills on a Calabi-Yau 3-fold. We show by construction how the resulting cohomological theory is related to the balanced…
