摘要：

Recently, the CDF and DO collaborations have claimed that the CP violating phase in B-s(0) - (B) over bar (0)(s) mixing is large, which is contrary to the expectations in the Standard Model. Such a large phase suggests New Physics contributions to B-s(0) - (B) over bar (0)(s) mixing. Motivated by this, we reevaluate the constraints on R-parity violating contributions, including baryon number violating couplings not considered before, to the mixing mass matrix element M-s(12) from the recent measurements of B-s(0) - (B) over bar (0)(s) mixing. We show that present data allow us to put quite strong constraints on both the magnitudes and the weak phases of the R-parity violating parameters. Some of these bounds are better than the existing ones, and some bounds are obtained for the first time. Near future experiments at the Tevatron, the LHC and B-factories can shrink or reveal the relevant parameter spaces of the R-parity violating couplings.
