High-Precision Charm-Quark Mass and QCD Coupling from Current-Current Correlators in Lattice and Continuum QCD
I. Allison, E. Dalgic, C. T. H. Davies +12
We use lattice QCD simulations, with MILC gluon configurations and HISQ c-quark propagators, to make very precise determinations of moments of charm-quark pseudoscalar, vector and…
Four Fermion Operator Matching with NRQCD Heavy and AsqTad Light Quarks
Elvira Gamiz, Junko Shigemitsu, Howard Trottier
We present one-loop matching coefficients between continuum and lattice QCD for the heavy-light four-fermion operators relevant for neutral B meson mixing both within and beyond th…
High Precision determination of the pi, K, D and D_s decay constants from lattice QCD
E. Follana, C. T. H. Davies, G. P. Lepage +1
We determine and decay constants from lattice QCD with 2% errors, 4 times better than experiment and previous theory: = 241(3) MeV, = 207(4) MeV and $f_{D…
B semileptonic decays with 2+1 dynamical quark flavors
Emel Gulez, Christine Davies, Alan Gray +3
We study semileptonic B decays, using MILC dynamical configurations with . NRQCD heavy and AsqTad light quark actions are used. We obtain the semileptonic form factors $f_…
Progress Calculating Decay Constants with NRQCD and AsqTad Actions
Matthew Wingate, Christine Davies, Alan Gray +3
We combine a light AsqTad antiquark with a nonrelativistic heavy quark to compute the decay constants of heavy-light pseudoscalar mesons using the ensemble of 3-flavor gauge field…
Heavy-light physics using NRQCD-staggered actions
Matthew Wingate, Junko Shigemitsu, G. Peter Lepage
One leading source of uncertainty in the lattice computation of semi-leptonic form factors in B decay, and to a lesser extent B meson decay constants, comes from the extrapolation…
