Description

The Bs -> µµ rare decay is one of the milestones of the flavor program at the LHC. The first evidence has been recently delivered by LHCb and further progress is expected in the near future. I will review the state-of-the-art knowledge of this observable within the SM, including the left-over systematics and its expected improvements. I will also discuss the impact of this observable on SM extensions, focusing on minimally model-dependent frameworks such as MFV or partial compositeness. It turns out that its constraining power is, depending on the framework, either comparably strong or strikingly stronger than that of Z-peak observables measured at LEP.
