The LHCb collaboration has measured lepton flavor universality (LFU) observables (RK and RK*) in semileptonic B decays recently. These measurements hint towards the breaking of lepton universality, a well tested feature built into the Standard Model. In this work we explore the possibility of explaining these anomalies within the framework of R-parity violating interactions. We show that RPV interactions allow new contributions to b → s μ μ transition which can explain the experimental values while satisfying the bounds coming from low-energy flavor data.
