Reevaluating R-parity Violating Supersymmetry Effects in B_s^0-\bar{B}_s^0 Mixing

Abstract

Recently, the CDF and DØ collaborations have claimed that the CP violating phase in $B_s^0-{\bar{B}}_s^0$ mixing is large, which is contrary to the expectations in the Standard Model. Such a large phase suggests New Physics contributions to $B_s^0-{\bar{B}}_s^0$ 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 $M_{12}^s$ from the recent measurements of $B_s^0-{\bar{B}}_s^0$ 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 exciting 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 R-parity violating couplings.
