Connected and disconnected quark contributions to hadron spin
A. J. Chambers, R. Horsley, Y. Nakamura +8
By introducing an external spin operator to the fermion action, the quark spin fractions of hadrons are determined from the linear response of the hadron energies using the Feynman…
Determining Sigma - Lambda mixing
R. Horsley, J. Najjar, Y. Nakamura +7
SU2 isospin breaking effects in baryon octet (and decuplet) masses are due to a combination of up and down quark mass differences and electromagnetic effects. These mass difference…
A lattice determination of Sigma - Lambda mixing
R. Horsley, J. Najjar, Y. Nakamura +7
Isospin breaking effects in baryon octet (and decuplet) masses are due to a combination of up and down quark mass differences and electromagnetic effects and lead to small mass spl…
A Feynman-Hellmann approach to the spin structure of hadrons
A. J. Chambers, R. Horsley, Y. Nakamura +8
We perform a Nf = 2 + 1 lattice QCD simulation to determine the quark spin fractions of hadrons using the Feynman-Hellmann theorem. By introducing an external spin operator to the…
Determination of the strange nucleon form factors
P. E. Shanahan, R. Horsley, Y. Nakamura +7
The strange contribution to the electric and magnetic form factors of the nucleon is determined at a range of discrete values of up to GeV. This is done by combinin…
Electric form factors of the octet baryons from lattice QCD and chiral extrapolation
P. E. Shanahan, A. W. Thomas, R. D. Young +7
We apply a formalism inspired by heavy baryon chiral perturbation theory with finite-range regularization to dynamical flavor CSSM/QCDSF/UKQCD Collaboration lattice QCD simul…
