A major challenge in modern particle physics is the search for signals beyond the Standard Model (SM), our current theory of the particle world. A series of recent experimental results, collectively known as the "b-anomalies" (named after the quark involved in these decays), have shown deviations from their theoretical predictions within the framework of the SM, indicating the potential presence of new laws of physics. To investigate these anomalies, two approaches are being pursued. The first approach aims to improve the precision of theoretical predictions and experimental measurements for already known phenomena, while the second approach seeks to identify new decay channels that are sensitive to the same signals of new physics. This talk focuses on the second approach by studying the decay of a Bs meson into two muons and a photon. A primary task presented here is a re-appraisal of the so-called "b-anomalies", followed by the description of the Bs→µµγ observable as a potential probe of these anomalies. However, measuring this decay poses a significant challenge due to the low energy of the photon. Therefore, a preliminary study of a method of partial reconstruction of the final state based solely on the two muons is presented at the LHCb experiment at the Large Hadron Collider (LHC) at CERN.
