Charm quark mass from inclusive semileptonic B decays

The MS¯ charm quark mass is determined to be m¯c(m¯c)=1224±17±54 MeV from a global fit to inclusive B meson decay data, where the first error is experimental, and includes the uncertainty in αs , and the second is an estimate of theoretical uncertainties in the computation. We discuss the implications of the pole mass renormalon in the determination of mc .
