BSM hadronic matrix elements for ε ′ /ε and K → ππ decays in the Dual QCD approach

Abstract We calculate for the first time all four-quark hadronic matrix elements of local operators possibly contributing to K → ππ decays and in particular to the ratio ε ′ /ε beyond the Standard Model (BSM). To this end we use the Dual QCD (DQCD) approach. In addition to 7 new mirror operators obt...
