Determining the charm-quark mass from current-current correlators in twisted mass lattice QCD — •Marcus Petschlies — Institut fuer Physik, Humboldt-Universitaet zu Berlin

We use the twisted mass lattice QCD formulation to estimate temporal moments of charm-quark current-current correlators, taking advantage of automatic O(a)-improvement. Using these moments in combination with up to four loop continuum perturbation theory we aim for a calculation of both the strong coupling constant and the charm quark mass with high precision.
