Description
Flavor-changing neutral currents, forbidden at tree level in the Standard Model, serve as sensitive indicators of new physics. A particularly promising channel is the decay $B_s^0\rightarrow\mu^+\mu^-\gamma$, which is unaffected by chiral suppression, unlike its nonradiative counterpart. Leveraging recent studies at LHCb, we introduce a novel detection technique that employs photon conversion in the VELO detector to analyze proton-proton collision data, corresponding to an integrated luminosity of $5.4\,\mathrm{fb}^{-1}$ at $\sqrt{s}=13\,\mathrm{TeV}$. This method aims to refine and extend the existing limits on the branching fraction, enhancing our understanding of the underlying physics.
