Chiral extrapolation of nucleon magnetic moments at next-to-leading-order
P. Wang, D. B. Leinweber, A. W. Thomas +1
Nucleon magnetic moments display a rich nonanalytic dependence on the quark mass in both quenched and full QCD. They provide a forum for a detailed examination of the connection be…
Finite-volume corrections to charge radii
J. M. M. Hall, D. B. Leinweber, B. J. Owen +1
The finite-volume nature of lattice QCD entails a variety of effects that must be handled in the process of performing chiral extrapolations. Since the pion cloud that surrounds ha…
Strong contribution to octet baryon mass splittings
P. E. Shanahan, A. W. Thomas, R. D. Young
We calculate the contribution to the mass splittings in baryonic isospin multiplets using SU(3) chiral perturbation theory and lattice QCD. Fitting isospin-averaged pertu…
Baryon resonances and hadronic interactions in a finite volume
J. M. M. Hall, A. C. -P. Hsu, D. B. Leinweber +2
In a finite volume, resonances and multi-hadron states are identified by discrete energy levels. When comparing the results of lattice QCD calculations to scattering experiments, i…
Volume Dependence of the Axial Charge of the Nucleon
N. L. Hall, A. W. Thomas, R. D. Young +1
It is shown that the strong volume-dependence of the axial charge of the nucleon seen in lattice QCD calculations can be understood quantitatively in terms of the pion-induced inte…
Charge Symmetry Breaking in Spin Dependent Parton Distributions and the Bjorken Sum Rule
I. C. Cloët, R. Horsley, J. T. Londergan +9
We present the first determination of charge symmetry violation (CSV) in the spin-dependent parton distribution functions of the nucleon. This is done by determining the first two…
