CP violation in three body B meson decays

Keri Vos, Siegen


Three-body decays, which form a large part of the B meson branching fraction, contain much more information than two-bdy decays, because of their non-trivial kinematic structure. Three-body decays can be described usng a QCD factorization framework similar to two-body decays, but involving additional hadronic inputs. Within this framework we prform a first study of CP violation in three-body decays. Experimental data shows a richt CP structure with large local CP asymmetries. We study if these measured CP patterns can be explained using our factorization framework.
