"A new perspective on CP violation in three body decays"

Presented by Monika Blanke, Cornell University

Wednesday, March 2, 2011, 2:00 pm — Small Seminar Room, Bldg. 510

I discuss the potential of measuring CP violation in three body decays, paying particular attention to the different possible origins of the "strong" CP-even phase. This phase can be obtained from the propagation of intermediate state particles - either when diagrams with different intermediate particles interfer, or when the intermediate state is off-shell by a different amount. I will elaborate mainly on the second case here which has not yet received much attention in the literature. After analysing a simple toy model I apply our findings to a specific example, namely neutralino decay in the MSSM.
