The recent measurement of Delta 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 Delta 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.
