摘要：

We perform a comprehensive study of the impact of new-physics operators with different Lorentz structures on CP-violating observables involving the b -> s mu(+)mu(-) transition. We examine the effects of new vector-axial vector (VA), scalar-pseudoscalar (SP) and tensor (T) interactions on the CP asymmetries in the branching ratios and forward-backward asymmetries of (B) over bar (0)(s) -> mu(+)mu(-), (B) over bar (0)(d) -> X-s mu(+)mu(-), (B) over bar (0)(s) -> mu(+)mu(-)gamma, (B) over bar (0)(d) -> (K) over bar mu(+)mu(-), and (B) over bar (0)(d) -> (K) over bar*mu(+)mu(-). In (B) over bar (0)(d) -> (K) over bar*mu(+)mu(-) we also explore the direct CP asymmetries in the longitudinal polarization fraction f(L) and the angular asymmetries A(T)((2)) and A(LT), as well as the triple-product CP asymmetries A(T)((im)) and A(LT)((im)). We find that, in almost all cases, the CP-violating observables are sensitive only to new physics which involves VA operators. The VA new physics may therefore be unambiguously identified by a combined analysis of future measurements of these CP-violating observables.
