Description

We analyse Bd,s → K(*)0K(*)0 modes within the SM, relating them in controlled way through SU (3)-flavoursymmetry and QCD-improved factorisation. We propose a set of sum rules for such penguin-mediated decays to constrain some CKM angles. We determine Bs → KK branching ratios and CP-asymmetries as functions of Adir(Bd → K0k0). Applying the same techniques to Bd,s → K* 0K*0, we outline strategies to determine the Bs mixing angle
