(CMS Collaboration). New structures in the formula presented mass spectrum in proton-proton collisions at formula presented. Physical Review Letters, 132(11).0031-9007https://doi.org/10.1103/PhysRevLett.132.111901https://hdl.handle.net/11492/8468PubMed ID: 38563916A 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. © 2024 CERN, for the CMS Collaboration.enArticle13211info:eu-repo/semantics/openAccess2-s2.0-85188184611WOS:0012021035000013856391610.1103/PhysRevLett.132.111901Q1N/A
