Calculation of a weak nonleptonic matrix element using ``Weinberg'' sum rules

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

There is a ``toy'' weak matrix element which can be expressed as an integral over the vector and axial vector spectral functions, ρV(s)ρA(s)\rho_V (s) - \rho_A (s). I review our recent evaluation of these spectral functions, the study of four ``Weinberg'' sum rules and the calculation of this matrix element.
