Contributions to ${b \rightarrow s \ell \ell}$ Anomalies from ${R}$-Parity Violating Interactions

Understand

We examine the parameter space of supersymmetric models with $R$-parity violating interactions of the form $\lambda' L Q D^c$ to explain the various anomalies observed in $b \rightarrow s \ell \ell$ transitions.

• To generate the appropriate operator in the low energy theory, we are led to a region of parameter space where loop contributions dominate.
• In particular, we concentrate on parameters for which diagrams involving winos, which have not been previously considered, give large contributions.
• Many different potentially constraining processes are analyzed, including $\tau \rightarrow \mu \mu \mu$, $B_s-\bar{B}_s$ mixing, $B \rightarrow K^{(*)} \nu \bar{\nu}$, $Z$ decays to charged leptons, and direct LHC searches.
