Unified gauge theories with right-handed currents and heavy fermions
Mohapatra, Rabindra N
Gauge models with heavy fermions and right-handed currents are discussed based on the gauge groups SU ( 2 ) A × U ( 1 ) × SU ( 4 ) ′ , SU ( 2 ) A × SU ( 2 ) B × SU ( 4 ) ′ , and SU(4) × SU ( 4 ) ′ and are constructed so as to lead to the Δ I = 1 2 rule. SU(4) × SU ( 4 ) ′ is advocated as the ultimate unifying gauge group of nature, and it is shown how at various stages of spontaneous breakdown both the SU ( 2 ) A × SU ( 2 ) B × SU ( 4 ) ′ and SU ( 2 ) A × U ( 1 ) × SU ( 4 ) ′ groups manifest themselves. We also show that CP violation takes an interesting complexion in these models and leads to exactly the relations η + - ≃ η 00 in K L → 2 π decays. Furthermore, we show that the magnitude of CP violation is related to gauge interactions that violate the heavy quark degeneracy.
