Leptoquarks meet ε ′/ε and rare Kaon processes
Abstract We analyse for the first time the CP violating ratio ε ′/ε in K → ππ decays in leptoquark (LQ) models. Assuming a mass gap to the electroweak (EW) scale, the main mechanism for LQs to contribute to ε ′ /ε is EW gauge-mixing of semi-leptonic into non-leptonic operators, which we treat in the...
