Rigorous QCD inequalities and the ∆I = 1/2 rule
Abstract
Rigorous QCD inequalities for operators involved in K > 2π weak transitions are derived, using the path integral formulation of the theory. The normal ordered part of the socalled (V  A)(V + A) penguin operators is shown to dominate over combinations of (V  A)(V + A) like operators when their K<>π matrix ele
