$R_{D^{(*)}}$ anomaly: A possible hint for natural supersymmetry with $R$-parity violation

Abstract

Recently, several BB-physics experiments have reported an appreciable deviation from the Standard Model (SM) in the tree-level observables RD()R_{D^{(*)}}; the combined weighted average now stands at 4σ\approx 4 \sigma. We first show the anomaly necessarily implies model-independent collider signals of the form ppbτνpp \to b \tau \nu that should be expediously searched for at ATLAS/CMS as a complementary test of the anomaly. Next we suggest a possible interconnection of the anomaly with the radiative stability of the Standard Model Higgs boson and point to a minimal effective supersymmetric scenario with RR-parity violation as the underlying cause. We also comment on the possibility of simultaneously explaining the recently reported RK()R_{K^{(*)}} anomaly in this setup.
