Three-loop QCD matching of the flavor-changing scalar current involving the heavy charm and bottom quark
Abstract We compute the matching coefficient between the quantum chromodynamics (QCD) and the non-relativistic QCD (NRQCD) for the flavor-changing scalar current involving the heavy charm and bottom quark, up to the three-loop order within the NRQCD factorization. For the first time, we obtain the a...
