High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

We present the recent investigation of the ΔS=1\Delta S = 1 effective weak chiral Lagrangian within the framework of the instanton-induced chiral quark model. Starting from the effective four-quark operators, we derive the effective weak chiral action by integrating out the constituent quark fields. Employing the derivative expansion, we obtain the effective weak chiral Lagrangian to O(p4){\cal O} (p^4) order with low energy constants.
