Windows on the hadronic vacuum polarisation contribution to the muon anomalous magnetic moment
C. T. H. Davies, C. DeTar, A. X. El-Khadra +11
An accurate determination of the leading-order hadronic vacuum polarisation (HVP) contribution to the anomalous magnetic moment of the muon is critical to understanding the size an…
Determination of quark masses from lattice QCD and the RI-SMOM intermediate scheme
A. T. Lytle, C. T. H. Davies, D. Hatton +2
We determine the charm and strange quark masses in the scheme, using lattice QCD calculations with highly improved staggered quarks (HISQ) and th…
Strong-isospin-breaking correction to the muon anomalous magnetic moment from lattice QCD at the physical point
Bipasha Chakraborty, C. T. H. Davies, C. DeTar +17
All lattice-QCD calculations of the hadronic-vacuum-polarization contribution to the muon's anomalous magnetic moment to-date have been performed with degenerate up- and down-quark…
Precision bottomonium properties and b quark mass from lattice QCD
C. T. H. Davies, D. Hatton, J. Koponen +2
As tests of QCD in the bottomonium system, we give the most accurate results to date for the ground-state hyperfine splitting and the leptonic width from full lattice QCD. The…
Hadronic-vacuum-polarization contribution to the muon's anomalous magnetic moment from four-flavor lattice QCD
C. T. H. Davies, C. DeTar, A. X. El-Khadra +15
We calculate the contribution to the muon anomalous magnetic moment hadronic vacuum polarization from {the} connected diagrams of up and down quarks, omitting electromagnetism. We…
Vector current renormalisation in momentum subtraction schemes using the HISQ action
D. Hatton, C. T. H. Davies, G. P. Lepage +1
As the only lattice vector current that does not require renormalisation is the point-split conserved current it is convenient to have a robust, precise and computationally cheap m…
