The charm quark mass from non-relativistic sum rules

We present an analysis to determine the charm quark mass from non-relativistic sum rules, using a combined approach taking into account fixed-order and effective-theory calculations. Non-perturbative corrections as well as higher-order perturbative corrections are under control. For the PS mass we find mPS(0.7 GeV)=1.50±0.04 GeVmPS(0.7 GeV)=1.50±0.04 GeV which translates into a MS¯ mass of m¯=1.25±0.04 GeV.
