CP Violation in the Neutral Kaon System — •Joachim Brod¹ and Martin Gorbahn² — ¹TTP, Uni Karlsruhe — ²TU München, IAS

The parameter є_K 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 B_K, 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.
