Implications of the LHCb discovery of CP violation in charm decays

The recent measurement of ∆A$_{CP}$ by the LHCb collaboration requires an 𝒪 (10) enhancement coming from hadronic physics in order to be explained within the SM. We examine to what extent can NP models explain ∆A$_{CP}$ without such enhancements. We discuss the implications in terms of a low energy...

description The recent measurement of ∆A$_{CP}$ by the LHCb collaboration requires an 𝒪 (10) enhancement coming from hadronic physics in order to be explained within the SM. We examine to what extent can NP models explain ∆A$_{CP}$ without such enhancements. We discuss the implications in terms of a low energy effective theory as well as in the context of several explicit NP models.
