B s mixing observables and |V td /V ts | from sum rules
Abstract We consider the effects of a non-vanishing strange-quark mass in the determination of the full basis of dimension six matrix elements for B s mixing, in particular we get for the ratio of the V − A Bag parameter in the B s and B d system: B ¯ Q 1 s / B ¯ Q 1 d = 0.987 − 0.009 + 0.007 $$ {\o...
