Abstract

The fourth generation can give the correct trend of Script SϕK0, Script Sπ0K0<sin 2ϕ1, as indicated by data, and the effect, being largely leading order, is robust against hadronic uncertainties. The effect on Script Sη'K0, however, is diluted away by hadronic effects, and Script Sη'K0 ≃ sin 2ϕ1 is expected. The near maximal arg V*t'sVt'b≲90° that is needed could resolve the unequal direct CP violation seen in B→K+π− and K+π0 modes, and is consistent with b→sℓ+ℓ− and Bs mixing constraints.
