Anomalous magnetic moment of the muon with dynamical QCD+QED
A. Westin, R. Horsley, W. Kamleh +8
The current discrepancy between experimental and Standard Model determinations of the anomalous magnetic moment of the muon can only be extended to the discove…
The strange quark contribution to the spin of the nucleon
R. Horsley, Y. Nakamura, H. Perlt +7
Quark line disconnected matrix elements of an operator, such as the axial current, are difficult to compute on the lattice. The standard method uses a stochastic estimator of the o…
Charmed states and flavour symmetry breaking
R. Horsley, Z. Koumi, Y. Nakamura +7
Extending the SU(3) flavour symmetry breaking expansion from up, down and strange sea quark masses to partially quenched valence quark masses allows an extrapolation to the charm q…
Electromagnetic form factors at large momenta from lattice QCD
A. J. Chambers, J. Dragos, R. Horsley +10
Accessing hadronic form factors at large momentum transfers has traditionally presented a challenge for lattice QCD simulations. Here we demonstrate how a novel implementation of t…
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…
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…
