Abstract

Time-dependent measurements of the decays Bs0(t) → φKs and Bd0(t) → K0K0 can be used to compare the weak phases of Bd0-Bd0 mixing and the t-quark contribution to the b → d penguin. Since these two phases are equal in the standard model, any discrepancy would be a sign of new physics, specifically in the b → d flavour-changing neutral current (FCNC). The method can be applied to other pairs of decays, such as Bs0(t) → J/ψKs and Bd0(t)→ J/ψπ0.
