ϵ ′/ϵ anomaly and neutron EDM in SU(2) L × SU(2) R × U(1) B−L model with charge symmetry

Abstract The Standard Model prediction for ϵ ′/ϵ based on recent lattice QCD results exhibits a tension with the experimental data. We solve this tension through W R + gauge boson exchange in the SU(2) L × SU(2) R × U(1) B−L model with ‘charge symmetry’, whose theoretical motivation is to attribute the chiral structure of the Standard Model to the spontaneous breaking of SU(2) R × U(1) B−L gauge group and charge symmetry. We show that MWR<58 $$ {M_W}_{{}_R}
