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…
QED effects in the pseudoscalar meson sector
R. Horsley, Y. Nakamura, H. Perlt +8
We present results on the pseudoscalar meson masses from a fully dynamical simulation of QCD+QED. We concentrate particularly on violations of isospin symmetry. We calculate the $π…
Disconnected contributions to the spin of the nucleon
A. J. Chambers, R. Horsley, Y. Nakamura +8
The spin decomposition of the proton is a long-standing topic of much interest in hadronic physics. Lattice QCD has had much success in calculating the connected contributions to t…
Wilson flow and scale setting from lattice QCD
V. G. Bornyakov, R. Horsley, R. Hudspith +8
We give a determination of the phenomenological value of the Wilson (or gradient) flow scales t0 and w0 for 2+1 flavours of dynamical quarks. The simulations are performed keeping…
Isospin splittings of meson and baryon masses from three-flavor lattice QCD + QED
R. Horsley, Y. Nakamura, H. Perlt +8
Lattice QCD simulations are now reaching a precision where isospin breaking effects become important. Previously, we have developed a program to systematically investigate the patt…
Reply to "Comment on `Lattice determination of Sigma - Lambda mixing' "
R. Horsley, J. Najjar, Y. Nakamura +7
In this Reply, we respond to the above Comment. Our computation [Phys. Rev. D 91 (2015) 074512] only took into account pure QCD effects, arising from quark mass differences, so it…
