Eradication of singularities in the next-to-leading order RG evolution for the ΔS = 1 effective Hamiltonian with 3 quark flavours

David H. Adams, Weonjong Lee

We consider the renormalization group evolution for the operators in the $\Delta S=1$ effective Hamiltonian with 3 active quark flavors, which is needed in the numerical analysis of data…
