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

Abstract

The recent measurements of the $B_s$ mass difference $\Delta M_s$ by the CDF and DØ collaborations are roughly consistent with the Standard Model predictions, therefore, these measurements will afford an opportunity to constrain new physics scenarios beyond the Standard Model. We consider the impact of the R-parity violating supersymmetry in the $B_s^0-{\bar{B}}_s^0$ mixing, and use the latest experimental results of $\Delta M_s$ to constrain the size of the R-parity violating tree level couplings in the $B_s^0-{\bar{B}}_s^0$ mixing. Then, using the constrained R-parity violating parameter space from $\Delta M_s$, we show the R-parity violating effects on the $B_s$ width difference $\Delta {\Gamma }_s$.
