RK(*) from RPV-SUSY sneutrinos

Abstract

We analyze the lepton flavor universality violation (LFV) in process b -> st+t-in an R-parity violating supersymmetric (RPV-SUSY) scenario. The most recent update on RK from the LHCb collaboration sug-gests approximately 3.1o- deviation from the Standard Model predictions, strengthening the case of LFV New Physics. In this work, we show that RK(*) 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.(c) 2022 The Author(s).
