Abstract

We analyze the lepton flavor universality violation (LFV) in process bs+b\to s \ell^+\ell^- in an R-parity violating supersymmetric (RPV-SUSY) scenario. The most recent update on \rk\rk from the LHCb collaboration suggests approximately 3.1σ3.1\sigma deviation from the Standard Model predictions, strengthening the case of LFV New Physics. In this work, we show that RK()R_{K^{(*)}} anomaly can be addressed via only sneutrinos within the framework of R-parity violating interactions assuming phenomenologically viable values of the couplings. While our proposed solution is by no means the only solution to these anomalies, it is a phenomenologically plausible one and, notably, quite a minimal one in the context of RPV-SUSY.
