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

TL;DR

This paper investigates how R-parity violating supersymmetry could influence $B_s$ meson mixing and decay, using recent experimental data to constrain new physics parameters and predict potential observable effects.

Contribution

It provides new constraints on R-parity violating couplings from $B_s$ mixing measurements and explores their effects on the $B_s$ width difference.

Findings

Constraints on R-parity violating couplings from $ riangle M_s$ data

Predicted effects of R-parity violation on $ riangle ext{Gamma}_s$

Potential for future experiments to detect R-parity violating signals

Abstract

The recent measurements of the $B_s$ mass difference $\Delta M_s$ by the CDF and D{\O} 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 $B^0_s-\bar{B}^0_s$ 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 $B^0_s-\bar{B}^0_s$ 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 $\Delta\Gamma_{s}$.
