Studying the $b\rightarrow s \ell^+\ell^-$ anomalies and $(g-2)_{\mu}$ in $R$-parity violating MSSM framework with the inverse seesaw mechanism

TL;DR

This paper investigates how an extended R-parity violating MSSM with the inverse seesaw mechanism can explain anomalies in B-meson decays and the muon g-2, providing a unified explanation consistent with various experimental constraints.

Contribution

It introduces a novel RPV-MSSM framework with inverse seesaw to simultaneously address B-decay anomalies and muon g-2 within a constrained parameter space.

Findings

The model can resolve B-decay anomalies and muon g-2 discrepancies.

Predictions include enhanced t→cg process detectable at FCC-hh.

Parameter space consistent with existing experimental bounds.

Abstract

Inspired by the recent experimental results which show deviations from the standard model (SM) predictions of $b\rightarrow s \ell^+\ell^-$ transitions, we study the $R$-parity violating minimal supersymmetric standard model (RPV-MSSM) extended by the inverse seesaw mechanism. The trilinear $R$-parity violating terms, together with the chiral mixing of sneutrinos, induce the loop contributions to the $b\rightarrow s \ell^+\ell^-$ anomaly. We study the parameter space of the single-parameter scenario $C^{\rm NP}_{9,\mu}=-C^{\rm NP}_{10,\mu}=C_{\rm V}$ and the double-parameter scenario $(C_{\rm V},C_{\rm U})$, respectively, constrained by other experimental data such as $B_s-\bar{B}_s$ mixing, $B\rightarrow X_s \gamma$ decay, the lepton flavour violating decays, etc. Both the single-parameter and the double-parameter scenario can resolve the long existing muon anomalous magnetic moment problem as well, and allow the anomalous $t\rightarrow cg$ process to reach the sensitivity at the Future Circular hadron-hadron Collider (FCC-hh).
