– 1– Fits for K 0

In recent years, K 0 L CP-violation experiments have improved our knowledge of CP-violation parameters and their consistency with the expectations of CP T invariance and uni-tarity. For definitions of K 0 L CP-violation parameters and a brief discussion of the theory, see the article " CP Violation " by L. Wolfenstein in the Reviews, Tables, and Plots section of this Review. This note describes...

Direct CP Violation in K L → π 0 e + e − Beyond Leading Logarithms ∗

We analyze the direct CP violation in the rare decay KL → π0e+e− with QCD effects taken into account consistently in the next-to-leading order. We calculate the two-loop mixing between the four-quark ∆S = 1 operators and the operator Q7V = (sd)V−A(ee)V in the NDR and HV renormalization schemes. Using the known two-loop anomalous dimension matrix of the four-quark operators, we find that the coe...

0 CP Violation – A Brief Review 1 Jonathan L . Rosner

Some past, present, and future aspects of CP violation are reviewed. The discrete symmetries C, P, and T are introduced with an example drawn from Maxwell’s Equations. The history of the discovery of CP violation in the kaon system is described briefly, and brought up-to-date with a review of recent results on kaon decays. The candidate theory of CP violation, based on phases in the Cabibbo-Kob...
