The mass of the b-quark from lattice NRQCD and lattice perturbation theory
A. J. Lee, C. J. Monahan, R. R. Horgan +3
We present a determination of the b-quark mass accurate through O(α_s^2) in perturbation theory and including partial contributions at O(α_s^3). Nonperturbative input comes from th…
Radiative improvement of spin and Darwin terms in the NRQCD action
T. C. Hammant, A. G. Hart, G. M. von Hippel +2
We present updated results for the radiative improvement of the σ.B term and the spin-dependent four-fermion terms in the lattice NRQCD action, and first results for the radiative…
Matching heavy-light currents with NRQCD and HISQ quarks
Christopher Monahan, Christine Davies, Ron Horgan +3
We calculate the one loop renormalisation parameters for the heavy-light axial-vector and vector currents using lattice perturbation theory. We use NonRelativistic QCD (NRQCD) heav…
Matching lattice and continuum axial-vector and vector currents with NRQCD and HISQ quarks
Christopher Monahan, Junko Shigemitsu, Ron Horgan
We match the continuum and lattice axial vector and vector currents at one loop in perturbation theory. For the heavy quarks we use the nonrelativistic QCD (NRQCD) action and for t…
