Abstract
There are currently two hints for new physics involving CP violation in b → s transitions: ΔS ≡ S f − S ϕKJ ≠ 0, and difference in direct CP asymmetry ΔA Kπ ≡ A 0K+π − A −K+π ≠ 0. We explore the two scenarios with a large and unique new CP phase in b ↔ s transitions. Motivated by ΔS ≠ 0, we update on the right-handed strange-beauty squark sb 1R at TeV scale. Motivated by ΔA Kπ ≠ 0, we explore sequential fourth generation t′ and b′ quarks. Both scenarios can survive constraints such as SM level b → sγ, sll and B s mixing, and predict sizable CP violation in B s mixing. The fourth generation picture predicts sizable K L → π 0vv. Direct search for sb R, b′ and t′ at hadronic colliders, such as Tevatron Run II and LHC, can complement further CP violation studies at these machines, as well as at the future Super B factory.

It turns out that, due to chiral enhancement, the LR and RL terms make numerical impact. This effect is included in actual computations
