摘要：We present an update of results fromthe HPQCD collaboration on charmphysics using the Highly
Improved Staggered Quark action. This includes a precise determination of mc using moments
of current-current correlators combined with high-order continuum QCD perturbation theory. We
also include an update on the determination of as from lattice QCD, preliminary results on the
determination of mb and a summary plot of the status of the gold-plated meson spectrum. There
is an appendix on tackling systematic errors in fitting using the Bayesian approach.
