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…
Partially conserved axial vector current and applications
R. Horsley, S. Kazmin, Y. Nakamura +5
We investigate implications of the use of the point-split axial vector current derived from a Wilson like fermionic action. We compute the corresponding renormalization factor nonp…
Flavour breaking effects in the pseudoscalar meson decay constants
V. G. Bornyakov, R. Horsley, Y. Nakamura +7
The SU(3) flavour symmetry breaking expansion in up, down and strange quark masses is extended from hadron masses to meson decay constants. This allows a determination of the ratio…
Determining the scale in Lattice QCD
V. G. Bornyakov, R. Horsley, R. Hudspith +8
We discuss scale setting in the context of 2+1 dynamical fermion simulations where we approach the physical point in the quark mass plane keeping the average quark mass constant. W…
Applications of the Feynman-Hellmann theorem in hadron structure
A. J. Chambers, R. Horsley, Y. Nakamura +8
The Feynman-Hellmann (FH) relation offers an alternative way of accessing hadronic matrix elements through artificial modifications to the QCD Lagrangian. In particular, a FH-motiv…
