Abstract

The study of regional CP asymmetry in Dalitz plots of charm (& beauty) decays gives us more information about the underlying dynamics than the ratio between total rates. In this paper we explore the consequences of the constraint from CPT symmetry with emphasis on three-body D decays. We show simulations of D±→π±K+K− and discuss correlations with measured D±→π±π+π−. There are important comments about analysis of recent LHCb data in CP asymmetries for B± decays to three-body final states.
