The hadronic vacuum polarization of the muon from four-flavor lattice QCD
C. T. H. Davies, C. E. DeTar, A. X. El-Khadra +16
We present an update on the ongoing calculations by the Fermilab Lattice, HPQCD, and MILC Collaboration of the leading-order (in electromagnetism) hadronic vacuum polarization cont…
Lattice QCD matrix elements for the width difference beyond leading order
Christine T. H. Davies, Judd Harrison, G. Peter Lepage +3
Predicting the width difference relies on the heavy quark expansion and on hadronic matrix elements of operators. We present the first lattice QCD…
Renormalising vector currents in lattice QCD using momentum-subtraction schemes
D. Hatton, C. T. H. Davies, G. P. Lepage +1
We examine the renormalisation of flavour-diagonal vector currents in lattice QCD with the aim of understanding and quantifying the systematic errors from nonperturbative artefacts…
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…
Neutral B-meson mixing from full lattice QCD at the physical point
R. J. Dowdall, C. T. H. Davies, R. R. Horgan +4
We calculate the bag parameters for neutral -meson mixing in and beyond the Standard Model, in full four-flavour lattice QCD for the first time. We work on gluon field configura…
Meson Electromagnetic Form Factors from Lattice QCD
C. T. H. Davies, J. Koponen, G. P. Lepage +2
Lattice QCD can provide a direct determination of meson electromagnetic form factors, making predictions for upcoming experiments at Jefferson Lab. The form factors are a reflectio…
