Calculation of the kaon B parameter using strictly local sum rules

  • 1. Mainz Univ. (Germany, F.R.). Inst. fuer Physik

Description

The kaon B-parameter is computed in the framework of strictly local QCD sum rules for a three-poin function involving pseudoscalar currents. As an application of these sum rules we derive a low energy formula for the B-parameter. We show that strictly local QCD sum rules yield more reliable results than other QCD sum rules, since they need less phenomenological information and do not suffer from stability problems. Our result for the B-parameter is B=0.74±0.17. (orig.)
