Description
Rare decays of heavy-quark hadrons provide a powerful way to probe indirectly for presence of phenomena beyond the Standard Model of particle physics.
At the LHCb experiment several ${b\to s\ell\ell}$ transitions, such as the rare decays $B\to K\ell\ell$ or ${B\to K^{*}\ell\ell}$, have been studied. They show tensions towards the Standard Model predictions in several observables, such as lepton universality ratios ($R_{K}$, $R_{K^{*}}$) or angular observables. So far most of the measurements have been focused on mesons and the $\Lambda_{b}$ baryon. To improve the understanding of the anomalies and widen the available knowledge, it is crucial to study ${b\to s\ell\ell}$ transitions for other weakly decaying baryons as well.
Therefore, the primary aim of the presented analysis is to observe the decay ${\Omega_{b}^{-} \to \Omega^{-}\mu^{-}\mu^{+}}$. If successful, the branching ratio relative to the decay ${\Omega_{b}^{-} \to \Omega^{-} J/\Psi(\to\mu^{-}\mu^{+})}$ will be measured.
The used data set corresponds to an integrated luminosity of ${9\:\mathrm{fb}^{-1}}$, which has been collected with the LHCb experiment from 2011 to 2018. In this talk the current status of the analysis is presented.
