Probe the R-Parity Violating Supersymmetry Effects in the B0s—B0s Mixing

  • The recent measurements of the Bs mass difference Δ Ms by the CDF and DO 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 B0s—B0s mixing, and use the latest experimental results of ΔMs to constrain the size of the R-parity violating tree level couplings in the B0s—B0s mixing. Then, using the constrained RPV parameter space from ΔMs, we show the R-parity violating effects on the Bs width difference ΔΓs.

Abstract: The recent measurements of the Bs mass difference Δ Ms by the CDF and DO 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 B0s—B0s mixing, and use the latest experimental results of ΔMs to constrain the size of the R-parity violating tree level couplings in the B0s—B0s mixing. Then, using the constrained RPV parameter space from ΔMs, we show the R-parity violating effects on the Bs width difference ΔΓs.
