Abstract
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.
