的Bs到mu mu伽马衰变提供了一个更广泛的有效运营商比其非辐射对应Bs到mu mu的敏感性，和一组有趣的是在当今的风味数据的差异。另一方面，直接测量的Bs到μ μ γ衰变提出了挑战，相对于Bs到μ μ之一。我们提出了一种新的策略，以寻找Bs到mu mu伽马衰变在非常事件的样本选择Bs到mu mu搜索。该方法包括提取Bs到μ μ γ谱作为Bs到μ μ γ谱的“污染”，因为后者的信号窗口相对于峰值区域向下延伸。我们提供的参数运行2数据的LHC的方法已经实际的实用性。
The Bs to mu mu gamma decay offers sensitivity to a wider set of effective operators than its non-radiative counterpart Bs to mu mu, 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 Bs to mu mu gamma decay poses challenges with respect to the Bs to mu mu one. We present a novel strategy to search for Bs to mu mu gamma decays in the very event sample selected for Bs to mu mu searches. The method consists in extracting the Bs to mu mu gamma spectrum as a "contamination" to the Bs to mu mu one, as the signal window for the latter is extended downward with respect to the peak region. We provide arguments for the actual practicability of the method already on Run-2 data of the LHC.
