Dalitz-plot dependence of CP asymmetry in B±→K±K+K−B±→K±K+K− decays

A large CP  -violating asymmetry predicted recently in the framework of the QCD factorization model for the B±→K±K+K−B±→K±K+K− decays in the range of the K+K−K+K− invariant masses above the ϕ(1020)ϕ(1020) resonance up to 1.4 GeV has been confirmed by the LHCb Collaboration. We discuss the emergence and size of this asymmetry in an extended model involving S- and P-waves together with the contribution from the D  -wave f2(1270)f2(1270) resonance and compare our model with the experimental data of the LHCb and BABAR Collaborations.
