Vacuum Insertion Approximation and the ΔI=1/2 rule: A lattice QCD test of the naïve factorization hypothesis for K, D, B and static mesons
Motivated by a recent paper by the RBC–UKQCD Collaboration, which observes large violations of the naïve factorization hypothesis in K→ππ decays, we study in this paper the accuracy of the Vacuum Insertion Approximation (VIA) for the matrix elements of the complete basis of four-fermion ΔF=2 operato...
