Probe the R-parity Violating Supersymmetry Effects in the B⁰ₛ-B⁰ₛ Mixing

Original · EN

The recent measurements of the Bₛ mass difference ΔMₛ 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 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 R-parity violating parameter space from ΔMₛ, we show the R-parity violating effects on the Bₛ width difference ΔΓₛ.
