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 novel approach to nonperturbative renormalization of singlet and nonsinglet lattice operators
A. J. Chambers, R. Horsley, Y. Nakamura +5
A novel method for nonperturbative renormalization of lattice operators is introduced, which lends itself to the calculation of renormalization factors for nonsinglet as well as si…
Renormalization of local quark-bilinear operators for Nf=3 flavors of SLiNC fermions
M. Constantinou, R. Horsley, H. Panagopoulos +5
The renormalization factors of local quark-bilinear operators are computed non-perturbatively for flavors of SLiNC fermions, with emphasis on the various procedures for the…
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…
