CP Violation Beyond the Standard Model
Abstract
Description
Recent developments concerning CP violation beyond the Standard Model are reviewed. The central target of this presentation is the $B$ system, as it plays an outstanding role in the extraction of CKM phases. Besides a general discussion of the appearance of new physics in the corresponding CP-violating asymmetries through $B^0_q$--$\bar{B^0_q}$ mixing $(q\in\{d,s\})$, it is emphasized that CP violation in non-leptonic penguin modes, e.g. in $B_d\toϕK_{S}$, offers a powerful tool to probe physics beyond the Standard Model. In this respect $B\toπK$ modes, which have been observed recently by the CLEO collaboration, may also turn out to be very useful. Their combined branching ratios allow us to constrain the CKM angle $γ$ and may indicate the presence of physics beyond the Standard Model.
