论文摘要
在相对较新的CMS数据中，暗示了与Muons质量28 GEV耦合的共振存在。这样的共振也应通过费米子环将其与光子搭配，因此可以在质子的超递碰撞（UPC）中搜索。我们从$μ^+μ^ - $ $ $^ - $ $ $^ - 在LHC的upc中的$xγγ$耦合常数上设置了上限。如果将来出现，我们的方法可以用于类似的共鸣。
In the relatively recent CMS data, there is a hint on the existence of a resonance with the mass 28 GeV coupling to muons. Such a resonance should also couple to photons through the fermion loop, therefore it can be searched for in ultraperipheral collisions (UPC) of protons. We set an upper bound on the $X γγ$ coupling constant from the data on $μ^+ μ^-$ pair production in UPC at the LHC. Our approach can be used for similar resonances should they appear in the future.
