Abstract
We show that, if a fourth generation is discovered at the Tevatron or LHC, one could study CP violation (CPV) in b′→s decays. Asymmetries could reach 30% for b′→sZ for mb′ 350GeV, while it could be greater than 50% for b′→sγ and extend to higher mb′. Branching ratios are 10-3-10-5, and CPV measurement requires tagging. Once measured, however, the CPV phase can be extracted with little theoretical uncertainty. © 2009 The American Physical Society.
