Charm quark mass from inclusive semileptonic B decays

Abstract 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 α s , 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 m c .
