$B_{s,d}^0 \to \mu\bar{\mu}$ and $B\to X_s\gamma$ in the R-parity violating MSSM

Understand

The recent measurements of $B_s^0 \to \mu\bar{\mu}$ decay candidates at the LHC consistent with the standard model rate, and the improving upper limits for $B_d^0 \to \mu\bar{\mu}$ can strongly constrain beyond the standard model physics.

• For example, in supersymmetric models with broken R-parity (RpV), they restrict the size of the new couplings.
• We use the combination of the public software packages SARAH and SPheno to derive new bounds on several combinations of R-parity violating couplings.
• We improve existing limits for the couplings which open tree-level decay channels and state new limits for combinations which induce loop contributions.
