Abstract

Recently the KTev Collaboration has measured Re(epsilon'/epsilon)=(28 +/- 4.1)x 10(-4) which is in agreement with early measurements from NA31. The Standard Model prediction for epsilon'/epsilon is On the lower end of the experimentally allowed range depending on models for hadronic matrix elements. In this paper we study the contributions from anomalous gauge couplings. We find that the contributions from anomalous couplings can be significant and can enhance epsilon'/epsilon to have a value closer to data. (C) 1999 Elsevier Science B.V. All rights reserved.
