A Lattice QCD Analysis of the Strangeness Magnetic Moment of the Nucleon
Derek B. Leinweber, Anthony W. Thomas
The outcome of the SAMPLE Experiment suggests that the strange-quark contribution to the nucleon magnetic moment, G_M^s(0), may be greater than zero. This result is very difficult…
A gerbe obstruction to quantization of fermions on odd dimensional manifolds with boundary
Alan Carey, Jouko Mickelsson
We consider the canonical quantization of fermions on an odd dimensional manifold with boundary, with respect to a family of elliptic hermitean boundary conditions for the Dirac ha…
Strong Isospin-Breaking Effects in K-->pi pi at Next-to-Leading Order in the Chiral Expansion
Carl E. Wolfe, Kim Maltman
Strong isospin-breaking (IB) contributions to both the octet and 27-plet weak K-->2 pi transitions are evaluated at next-to-leading order (NLO) in the chiral expansion. NLO contrib…
Symanzik Improvement In The Static Quark Potential
Frederic D. R. Bonnet, Derek B. Leinweber, Anthony G. Williams +1
A systematic investigation of Symanzic improvement in the gauge field action is performed for the static quark potential in quenched QCD. We consider Symanzik improved gauge field…
Comment on ``Parton distributions, d/u, and higher twist effects at high x''
W. Melnitchouk, I. R. Afnan, F. Bissey +1
In a recent paper Yang and Bodek extracted the free neutron structure function at large x by extrapolating the density dependence of the nuclear EMC ratios to the deuteron. We clar…
1/m_Q Corrections to the Bethe-Salpeter Equation for Λ_{Q} in the Diquark Picture
X. -H. Guo, A. W. Thomas, A. G. Williams
Corrections of order 1/m_Q (Q=b or c) to the Bethe-Salpeter (B-S) equation for Λ_Q are analyzed on the assumption that the heavy baryon Λ_Q is composed of a heavy quark and a scala…
Modeling the April 1997 flare of Mkn 501
A. Muecke, R. J. Protheroe
The April 1997 giant flare of Mkn 501 is modelled by a stationary Synchrotron-Proton-Blazar model. Our derived model parameters are consistent with X-ray-to-TeV-data in the flare s…
Scaling law for the electromagnetic form factors of the proton
D. H. Lu, S. N. Yang, A. W. Thomas
The violation of the scaling law for the electric and magnetic form factors of the proton are examined within the cloudy bag model. The suppression of the ratio of the electric and…
Twisted index theory on good orbifolds, I: noncommutative Bloch theory
Matilde Marcolli, Varghese Mathai
This paper, together with Part II, expands the results of math.DG/9803051. In Part I we study the twisted index theory of elliptic operators on orbifold covering spaces of compact…
Dynamics of competition between collectivity and noise in the stock market
S. Drozdz, F. Gruemmer, F. Ruf +1
Detailed study of the financial empirical correlation matrix of the 30 companies comprised by DAX within the period of the last 11 years, using the time-window of 30 trading days,…
A Multi-Component Measurement of the Cosmic Ray Composition Between 10^{17} eV and 10^{18} eV
T. Abu-Zayyad, K. Belov, D. J. Bird +45
The average mass composition of cosmic rays with primary energies between eV and eV has been studied using a hybrid detector consisting of the High Resolution Fly…
Spectra of Baryons Containing Two Heavy Quarks in Potential Model
Sheng-Ping Tong, Yi-Bing Ding, Xin-Heng Guo +4
In this work, we employ the effective vertices for interaction between diquarks (scalar or axial-vector) and gluon where the form factors are derived in terms of the B-S equation,…
Index of a family of lattice Dirac operators and its relation to the non-abelian anomaly on the lattice
David H. Adams
In the continuum, a topological obstruction to the vanishing of the non-abelian anomaly in 2n dimensions is given by the index of a certain Dirac operator in 2n+2 dimensions, or eq…
Energy Estimation of UHE Cosmic Rays using the Atmospheric Fluorescence Technique
C. Song, Z. Cao, B. R. Dawson +3
We use the CORSIKA air shower simulation program to review the method for assigning energies to ultra-high energy (UHE) cosmic rays viewed with the air fluorescence technique. This…
On a Schwarzian PDE associated with the KdV Hierarchy
Frank Nijhoff, Andrew Hone, Nalini Joshi
We present a novel integrable non-autonomous partial differential equation of the Schwarzian type, i.e. invariant under Möbius transformations, that is related to the Korteweg-de V…
The quark propagator in momentum space
J. I. Skullerud, A. G. Williams
The quark propagator is calculated in the Landau gauge at beta=6.0. A method for removing the dominant, tree-level lattice artefacts is presented, enabling a calculation of the mom…
On the search for a narrow penta-quark Z baryon in NN interactions
M. V. Polyakov, A. Sibirtsev, K. Tsushima +2
The possibility for an observation of a narrow penta-quark baryon in reactions is discussed. It is shown that the reaction at excess energies around 100…
Chiral Corrections to Baryon Masses Calculated within Lattice QCD
Anthony W. Thomas, Derek B. Leinweber, Kazuo Tsushima +1
Consideration of the analytic properties of pion-induced baryon self energies leads to new functional forms for the extrapolation of light baryon masses. These functional forms rep…
