Quark-tadpole origin of the ΔI = 1/2 rule
Description
In the context of a two-quark field picture of current quarks and renormalized constituent quarks, we show that an s-d current-quark tadpole generated by the weak Cabibbo-GIM current appears in the current-quark nonleptonic ΔY = 1 hamiltonian. Then we demonstrate that this ΔI = 1/2 operator in fact sets the observed scale of the Ksub(s) → ππ decays without recourse to any fitted parameters. (orig.)
