Renormalization group evolution for the ΔS=1 effective Hamiltonian with Nf=2+1
We discuss the renormalization group (RG) evolution for the ΔS=1 operators in unquenched QCD with N f =3 (m u =m d =m s ) or, more generally, N f =2+1 (m u =m d ≠m s ) flavors. In particular, we focus on the specific problem of how to treat the singularities which show up only for N f =3 or N...
