Abstract

We analyze the lepton flavor universality violation (LFV) in process b→sℓ⁺ℓ⁻ in an R-parity violating supersymmetric (RPV-SUSY) scenario. The most recent update on R_K from the LHCb collaboration suggests approximately 3.1σ deviation from the Standard Model predictions, strengthening the case of LFV New Physics. In this work, we show that 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.
