Mass effects in QCD corrections of weak decays

QCD corrections to the weak decay rate of a quarks are calculated taking full account of all the masses involved. The corrections are quite sensitive to the masses and change sign in most of the cases. Unexpectedly enough, in the whole range of the final fermion masses, the effects substantially enh...

Description
Summary:QCD corrections to the weak decay rate of a quarks are calculated taking full account of all the masses involved. The corrections are quite sensitive to the masses and change sign in most of the cases. Unexpectedly enough, in the whole range of the final fermion masses, the effects substantially enhance the rate compared to its zero-mass limit.
