Bs0→μ+μ−γ from Bs0→μ+μ−
The Bs0→μ+μ−γ decay offers sensitivity to a wider set of effective operators than its non-radiative counterpart Bs0→μ+μ−, and a set that is interesting in the light of present-day discrepancies in flavour data. On the other hand, the direct measurement of the Bs0→μ+μ−γ decay poses challenges with re...

We present a novel strategy to search for Bs0→μ+μ−γ decays in the very event sample selected for Bs0→μ+μ− searches.
