摘要：
We study B physics phenomenology in the scenario of split supersymmetry without R parity. By assuming the constraints of bilinear (trilinear) R-parity violating couplings, which are introduced to solve the problem of the atmospheric (solar) neutrino mass, we show that the decay branching ratios of B-s -> l(+)l(-) and the mixing of B-s-(B) over bar (s) can be large. Explicitly, we find that B(B-s ->mu(+)mu(-))=O(10(-7)) and Delta m(Bs)=O(10(-9)) GeV, which should be observed at future hadron colliders.
