Acceleration and Interaction of Ultra High Energy Cosmic Rays
R. J. Protheroe
In this chapter I give an overview of shock acceleration, including a discussion of the maximum energies possible and the shape of the spectrum near cut-off, interactions of high e…
Chiral symmetry and properties of hadron correlators in matter
Boris Krippa
The constraints imposed by chiral symmetry on hadron correlation functions in nuclear medium are discussed. It is shown that these constraints implies the certain structure of the…
Pion Exchange and the H1 Forward Spectrometer Data
A. W. Thomas, C. Boros
We point out that the component of the nucleon wave function is vital to the interpretation of the recent H1 data for leading baryon production. While the ratio is equal…
On the cosmic ray bound for models of extragalactic neutrino production
K. Mannheim, R. J. Protheroe, J. P. Rachen
We obtain the maximum diffuse neutrino intensity predicted by hadronic photoproduction models of the type which have been applied to the jets of active galactic nuclei or gamma ray…
Precise strength of th piNN coupling constant
T. E. O. Ericson, B. Loiseau, J. Rahm +3
We report here a preliminary value for the piNN coupling constant deduced from the GMO sumrule for forward piN scattering. As in our previous determination from np backward differe…
Bäcklund transformations for the second Painlevé hierarchy: a modified truncation approach
Peter A. Clarkson, Nalini Joshi, Andrew Pickering
The second Painlevé hierarchy is defined as the hierarchy of ordinary differential equations obtained by similarity reduction from the modified Korteweg-de Vries hierarchy. Its fir…
Chiral symmetry breaking in dimensionally regularized nonperturbative quenched QED
V. P. Gusynin, A. W. Schreiber, T. Sizer +1
In this paper we study dynamical chiral symmetry breaking in dimensionally regularized quenched QED within the context of Dyson-Schwinger equations. In D < 4 dimensions the theory…
Eta, Omega and Charmed Mesic Nuclei
K. Tsushima
Using the quark-meson coupling (QMC) model, we investigate theoretically whether and mesons form meson-nucleus bound states. We study several nuclei from He to $^{208…
TeV gamma-ray observations of southern BL Lacs with the CANGAROO 3.8m Imaging Telescope
M. D. Roberts, S. A. Dazeley, P. G. Edwards +32
Observational and theoretical results indicate that low-redshift BL Lacertae objects are the most likely extragalactic sources to be detectable at TeV energies. In this paper we pr…
Lattice study of the Kink soliton and the zero-mode problem for phi4 in two dimensions
A. Ardekani, A. G. Williams
We study the kink solion and the zero-mode contribution to the Kink soliton mass in regions beyond the semiclassical regime. The calculations are done in the non-trivi…
Spectral change of sigma and omega mesons in a dense nuclear medium
K. Saito, K. Tsushima, A. W. Thomas
The spectra of the scalar () and vector () mesons in nuclear matter are studied in detail using the quark-meson coupling (QMC) model. It is shown that above normal nuclear ma…
Asymptotic Scaling and Infrared Behavior of the Gluon Propagator
D. B. Leinweber, J. I. Skullerud, A. G. Williams +1
The Landau gauge gluon propagator for the pure gauge theory is evaluated on a 32^3x64 lattice with a physical volume of (3.35^3x6.7)fm^4. Comparison with two smaller lattices at di…
The Feynman Variational Principle in the Worldline Representation of Field Theory
R. Rosenfelder, C. Alexandrou, A. W. Schreiber
Following Feynman's treatment of the non-relativistic polaron problem, similar techniques are used to study relativistic field theories: after integrating out the bosonic degrees o…
High energy neutrino astrophysics
R. J. Protheroe
I give a brief discussion of possible sources of high energy neutrinos of astrophysical origin over the energy range from eV to eV. In particular I sh…
Isospin-Breaking Vector Meson Decay Constants From Continuous Families of Finite Energy Sum Rules
Kim Maltman, Carl E. Wolfe
The isospin-breaking vector meson decay constants are determined from a QCD sum rule analysis of the vector current correlator , using a recently proposed im…
J/Ψproduction in πN collisions
A. Sibirtsev, K. Tsushima
We calculate the total cross section for based on -meson exchange. On the basis of this calculation we predict a maximal reaction rate arising from the OZI-violati…
Evidence for Charge Symmetry Violation in Parton Distributions
C. Boros, J. T. Londergan, A. W. Thomas
By comparing structure functions measured in neutrino and charged lepton deep inelastic scattering, one can test the validity of parton charge symmetry. New experiments allow us to…
The role of the in the reaction
A. Sibirtsev, K. Tsushima, W. Cassing +1
Using the resonance model, which was successfully applied for the study of the reaction, we investigate reactions that should provide cleaner informatio…
Fock terms in the quark-meson coupling model
G. Krein, A. W. Thomas, K. Tsushima
The mean field description of nuclear matter in the quark-meson coupling model is improved by the inclusion of exchange contributions (Fock terms). The inclusion of Fock terms allo…
Spin Dependent Parton Distributions in a Bound Nucleon
F. M. Steffens, K. Tsushima, A. W. Thomas +1
The determination of the spin distribution functions for the neutron requires an understanding of the changes induced by a nuclear medium. We present the first estimates of the cha…

K. Tsushima, D. H. Lu, A. W. Thomas +2
We show that the D^- meson will form narrow bound states with ^{208}Pb. Mean field potentials for the D^0, D^0-bar and D^- in ^{208}Pb are calculated self-consistently using the qu…
