title = "Decay constants fB and fBs and quark masses mb and mc from HISQ simulations",
abstract = "We present a progress report on our calculation of the decay constants fB and fBs from lattice- QCD simulations with highly-improved staggered quarks. Simulations are carried out with several heavy valence-quark masses on (2+1+1)-flavor ensembles that include charm sea quarks. We include data at six lattice spacings and several light sea-quark masses, including an approximately physical-mass ensemble at all but the smallest lattice spacing, 0.03 fm. This range of parameters provides excellent control of the continuum extrapolation to zero lattice spacing and of heavy-quark discretization errors. Finally, using the heavy-quark effective theory expansion we present a method of extracting from the same correlation functions the charm- and bottom-quark masses as well as some low-energy constants appearing in the heavy-quark expansion.",
