摘要

A search is reported for near-threshold structures in the Formula Presented invariant mass spectrum produced in proton-proton collisions at Formula Presented from data collected by the CMS experiment, corresponding to an integrated luminosity of Formula Presented. 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 Formula Presented. Another structure with even higher significance is found at a mass of Formula Presented, which is consistent with the Formula Presented 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 Formula Presented. 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.
