CP Violation in the Neutral Kaon System — •Joachim Brod1 and Martin Gorbahn2 — 1TTP, Uni Karlsruhe — 2TU München, IAS
The parameter єK describes CP violation in the mixing of neutral K-Mesons. It is an important ingredient in the standard analysis of the unitarity triangle.
Recent progress in the lattice calculation of BK, parameterising the long distance effects in neutral Kaon mixing, have made a NNLO calculation of the short distance contributions mandatory.
I will discuss this calculation and present first results.
