Precision charm physics, mc and alphas from lattice QCD
Abstract
We present an update of results from the HPQCD collaboration on charm physics 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 alphas 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.
