Abstract: (arXiv)
We describe a novel use of the Dalitz plot to probe CP symmetry in three-body modes of BB and DD mesons. It is based on an observable inspired by astronomers' practice, namely the significance in the difference between corresponding Dalitz plot bins. It provides a model independent mapping of local CP asymmetries. We illustrate the method for probing CP symmetry in the complementary cases of B decays, where sizable or even large effects can be expected, yet have to be differentiated against leading Standard Model contributions, and DD decays, where one cannot count on sizable effects, yet has to deal with much less Standard Model background.
