Abstract: Inspired by the recent experimental results which show deviations from the standard model predictions of $b\ensuremath{\rightarrow}s{\ensuremath{\ell}}^{+}{\ensuremath{\ell}}^{\ensuremath{-}}$ transitions, we study the $R$-parity violating minimal supersymmetric standard model 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 $b\ensuremath{\rightarrow}s{\ensuremath{\ell}}^{+}{\ensuremath{\ell}}^{\ensuremath{-}}$ anomaly. We study the parameter space of the single-parameter scenario ${C}_{9,\ensuremath{\mu}}^{\mathrm{NP}}=\ensuremath{-}{C}_{10,\ensuremath{\mu}}^{\mathrm{NP}}={C}_{\mathrm{V}}$ and the double-parameter scenario $({C}_{\mathrm{V}},{C}_{\mathrm{U}})$, respectively, constrained by other experimental data such as ${B}_{s}\ensuremath{-}{\overline{B}}_{s}$ mixing, $B\ensuremath{\rightarrow}{X}_{s}\ensuremath{\gamma}$ decay, the lepton flavor 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 $t\ensuremath{\rightarrow}cg$ process to reach the sensitivity at the Future Circular hadron-hadron Collider.
