文摘

Rare heavy-flavour decays are an ideal place to search for the effects of potential new particles that modify the decay rates or the Lorentz structure of the decay vertices. Recent results on Flavour Changing Neutral Current decays from the LHC are reviewed. An emphasis is put on the very rare decay the MathML source" class="mathImg" data-mathURL="/science?_ob=MathURL&_method=retrieve&_eid=1-s2.0-S2405601415004964&_mathId=si1.gif&_user=111111111&_pii=S2405601415004964&_rdoc=1&_issn=24056014&md5=807d7caf48ef3f3794277b9c3ae0ad2c">the MathML source" title="View the MathML source" src="/sd/grey_pxl.gif" data-inlimgeid="1-s2.0-S2405601415004964-si1.gif">$B_s^0\to {\mu }^{+}{\mu }^{-}$, which was recently observed by the CMS and LHCb experiments, on a recent test of lepton universality in loop processes and on the analysis of the angular distributions of the the MathML source">B⁰→K^⁎0μ⁺μ⁻$B^0\to K^{⁎0}{\mu }^{+}{\mu }^{-}$ decays, both by the LHCb collaboration.
