Calculation of a weak nonleptonic matrix element using ``Weinberg'' sum rules
Abstract
Description
There is a ``toy'' weak matrix element which can be expressed as an integral over the vector and axial vector spectral functions, $ρ_V (s) - ρ_A (s)$. I review our recent evaluation of these spectral functions, the study of four ``Weinberg'' sum rules and the calculation of this matrix element.
