Abstract

We calculate the next-to-leading order (NLO) quantum chromodynamics (QCD) corrections to the inclusive process of Z0Bc*+c¯+b under the nonrelativistic QCD (NRQCD) factorization scheme. Technical details about contributions from vector and axial-vector currents in a dimensional regularization scheme are discussed. Numerical calculation shows that the NLO correction enhances the leading-order decay width by about 50%, and the dependence on renormalization scale μ is reduced. The uncertainties induced by quark masses and the renormalization scale μ are also analyzed.
