CP Violation in three-body B meson decays

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