Running charm quark mass versus $M_D$ and the $D_{(s)}\to \mu\nu$ decay
I study (for the first time) the dependence of M_D and of the leptonic decay constant f_D on the variation of the running charm quark mass m_c(\nu). I conclude that the present data on f_{D_s} from D_s into \mu\nu decay give a weaker constraint than M_D, where the latter leads to the result, m_c(M_c...
