Two-loop QCD corrections to Bc meson leptonic decays
The two-loop quantum chromodynamics (QCD) radiative corrections to the Bc meson leptonic decay rate are calculated in the framework of the non-relativistic QCD (NRQCD) factorization formalism. Two types of master integrals appearing in the calculation are obtained analytically for the first time. We...
