Explaining the Lepton Non-universality at the LHCb and CMS from a Unified Framework

TL;DR

This paper proposes a unified supersymmetric framework with R-parity violation to explain recent anomalies observed at LHCb and CMS, linking lepton non-universality and W-boson searches.

Contribution

It introduces a specific combination of R-parity violating operators that simultaneously accounts for anomalies in B-meson decays and W-boson search results.

Findings

The model explains the LHCb lepton non-universality anomaly.

It also accounts for the CMS excess in the $eejj$ channel.

Provides a unified supersymmetric explanation for two separate anomalies.

Abstract

The recent results from the LHCb in the context of $(B^+ \rightarrow K^+ l l)$ decay and the CMS analysis in the context of right handed $W$-boson ($W_R$) search show a $2.6\sigma$ and a $2.8\sigma$ deviations from the Standard Model expectations respectively. In this work, we address these two seemingly uncorrelated results in the context of \R-parity violating supersymmetry. We found that a particular combination of $LQD^c$-type operators which successfully explain the LHCb result, can also accommodate the CMS excess in the $eejj$ channel of the $W_R$ search.
