New Structures in the Mass Spectrum in Proton-Proton Collisions at
A search is reported for near-threshold structures in the invariant mass spectrum produced in proton-proton collisions at from data collected by the CMS experiment, corresponding to an integrated luminosity of . Three structures are found, and a model with quantum interference among these structures provides a good description of the data. A new structure is observed with a local significance above 5 standard deviations at a mass of . Another structure with even higher significance is found at a mass of , which is consistent with the resonance reported by the LHCb experiment and confirmed by the ATLAS experiment. Evidence for another new structure, with a local significance of 4.7 standard deviations, is found at a mass of . Results are also reported for a model without interference, which does not fit the data as well and shows mass shifts up to 150 MeV relative to the model with interference.
