Explaining the $R_K$ and $R_{K^{\ast }}$ Anomalies With Right-handed Sneutrino

Abstract

The recent intriguing measurements of $R_K$ and $R_{K^{\ast }}$ are important hints of new physics that violates lepton universality. We analyze the semileptonic decays $b\to s{\ell }^{+}{\ell }^{-}$ in the framework of the $B-L$ extension of Minimal Supersymmetric Standard Model (MSSM) with Inverse Seesaw (BLSSMIS). A salient feature of this model is that one of the right-handed sneutrino can be light and the neutrino Yukawa couplings are of order one. We show that the box diagram mediated by right-handed sneutrino, higgsino-like chargino, and light stop can account simultaneously for both $R_K$ and $R_{K^{\ast }}$. Therefore, while the MSSM cannot explain the $R_K$ and $R_{K^{\ast }}$ anomalies, the BLSSMIS can account for them, where a significant lepton flavor non-universality might stem from large neutrino Yukawa couplings.
