چکیده
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 αs 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.

Precision charmonium and D physics from lattice QCD and determination of the charm quark mass
I will describe recent results from the HPQCD collaboration using a new very accurate method for charm quarks in lattice QCD, that we have used in calculations including the full effect of u, d and s sea quarks. Multiple values of the lattice spacing and of the u, d and s sea quark masses allow us to extrapolate reliably, with a full error budget, to the real world. This opens up the field of c...
متن کاملCharm Physics with Bes-iii at Bepc-ii
We report on the charm physics potential at BES-III at BEPC-II which will make significant contribution to quark flavor physics this decade. The charm physics program will include studies of leptonic, semileptonic and hadronic charm decays, and tests for physics beyond the Standard Model. Event samples of the order of 30 million DD pairs, 2 million D S D− S pairs at threshold and 10 × 10 J/ψ de...
متن کاملWG V Conveners ’ Report : Charm Inputs for CKM Physics
We introduce the contributions to the proceedings of Working Group V. The main topics were: present and future experiments dedicated to charm physics, the interplay between high-precision measurements and better control over theoretical uncertainties, and searches for signals of new physics in the charm sector. The comparison of Lattice QCD calculations with precise measurements of charm semi-l...
متن کاملReview of Charm Semileptonic Decays and QCD
The semileptonic decays of charm mesons provide an ideal environment to refine the QCD physics. The decay rates are computed from the first principles using Cabbibo-Kobayashi-Maskawa quark-mixing matrix elements. The hadronic complications are contained in the form factors, which are calculable via non-perturbative Lattice QCD, HQET or quark models. With the rapid advance in the computer techno...
متن کاملThe Physics of Charm: Recent Experimental Results
We review the most recent results from experiments studying systems containing charmed quarks. The selection reflects the presenter’s bias, and there is an emphasis on decays of open charm. We discuss precision measurements of various sorts, various new states in the charmonium system, measurements aimed at testing Lattice QCD, and the latest searches for charm mixing. We conclude with a discus...
