ϵ′/ϵ from charged-Higgs-induced gluonic dipole operators

We study the effect of charged-Higgs-induced chromomagnetic operator, Q8G(−)≡s¯σμνTaγ5dGaμν, on the Kaon direct CP violation Re(ϵ′/ϵ). Using the matrix element 〈ππ|O8G(−)|K0〉 recently obtained by a large Nc dual QCD approach, we find that if the Kobayashi–Maskawa phase is the origin of CP violation,...
