Semileptonic weak Hamiltonian to O $$ \mathcal{O} $$ (αα s ) in momentum-space subtraction schemes

Abstract The CKM unitarity precision test of the Standard Model requires a systematic treatment of electromagnetic and strong corrections for semi-leptonic decays. Electromagnetic corrections require the renormalization of a semileptonic four-fermion operator. In this work we calculate the O $$ \mat...
