Twisted mass QCD in the charm sector
Presenter: Benoit Blossier — DESY Zeuthen
We present the measurement on the lattice (Nf=2) of the charm quark mass mc, the decay constant fD and the ratio fDs/fD. Valence and sea quarks are described with tmQCD action at maximal twist, so that the theory is O(a) improved. Two simulations with a lattice spacing quite smaller than 0.1 fm have been performed, in order to study the scaling properties.
