OPE, charm-quark mass, and decay constants of D and [Formula: see text] mesons from QCD sum rules

We present a sum-rule extraction of the decay constants of the charmed mesons D and [Formula: see text] from the two-point correlator of pseudoscalar currents. First, we compare the perturbative expansion for the correlator and the decay constant performed in terms of the pole and the running [Formu...
