摘要：

There are currently two hints for new physics involving CP violation in b -> s transitions: Delta S equivalent to S-f - S-j/psi K not equal 0, and difference in direct CP asymmetry Delta A(K pi) equivalent to A(K+pi 0) - A(K+pi-) not equal 0. We explore the two scenarios with a large and unique new CP phase in b 4 s transitions. Motivated by AS : 0, we update on the right-handed strange-beauty squark (s) over tildeb(1R) at TeV scale. Motivated by Delta A(K pi) not equal 0, we explore sequential fourth generation t' and b' quarks. Both scenarios can survive constraints such as SM level b -> s gamma, sll and B-s mixing, and predict sizable CP violation in B-s mixing. The fourth generation picture predicts sizable K-L -> pi(0)nu nu. Direct search for (s) over tildeb(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.
