Charged multi-hadron systems in lattice QCD+QED
S. R. Beane, W. Detmold, R. Horsley +13
Systems with the quantum numbers of up to twelve charged and neutral pseudoscalar mesons, as well as one-, two-, and three-nucleon systems, are studied using dynamical lattice quan…
Scaling and higher twist in the nucleon Compton amplitude
A. Hannaford-Gunn, R. Horsley, Y. Nakamura +7
The partonic structure of hadrons plays an important role in a vast array of high-energy and nuclear physics experiments. It also underpins the theoretical understanding of hadron…
Electromagnetic contribution to - mixing using lattice QCD+QED
Z. R. Kordov, R. Horsley, Y. Nakamura +6
Mixing in the - system is a direct consequence of broken isospin symmetry and is a measure of both isospin-symmetry breaking as well as general SU(3)-flavour symmetry bre…
Isospin splittings in the decuplet baryon spectrum from dynamical QCD+QED
R. Horsley, Z. Koumi, Y. Nakamura +8
We report a new analysis of the isospin splittings within the decuplet baryon spectrum. Our numerical results are based upon five ensembles of dynamical QCD+QED lattices. The analy…
Nucleon structure functions from lattice operator product expansion
A. J. Chambers, R. Horsley, Y. Nakamura +7
Deep-inelastic scattering, in the laboratory and on the lattice, is most instructive for understanding how the nucleon is built from quarks and gluons. The long-term goal is to com…
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…
