Popis: | In the relatively recent CMS data, there is a hint on the existence of a resonance with the mass 28 GeV decaying to a μ+μ− pair and produced in association with a b quark jet and a second jet. 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 Xγγ 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. |
