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…
