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…
Precise Determinations of the Decay Constants of B and D mesons
Heechang Na, Chris Monahan, Christine Davies +4
Recently we studied the B, Bs, D and Ds meson decay constants using various treatments for the heavy quark. For B mesons, we determined fB, fBs, and fBs/fB with NRQCD bottom quarks…
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…
Form factors for B and B_s semileptonic decays with NRQCD/HISQ quarks
C. M. Bouchard, G. Peter Lepage, Chris J. Monahan +2
We discuss preliminaries of a calculation of the form factors for the semileptonic decays B -> pi lv, B_s -> K lv, and B -> K ll. We simulate with NRQCD heavy and HISQ light valenc…
The Beauty of Lattice Perturbation Theory: The Role of Lattice Perturbation Theory in B Physics
Christopher Monahan
As new experimental data arrive from the LHC the prospect of indirectly detecting new physics through precision tests of the Standard Model grows more exciting. Precise experimenta…
