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.eninfo:eu-repo/semantics/openAccessMass spectrometryStatisticsATLAS experimentIntegrated luminosityInvariant-mass spectraMass shiftMass spectraNear thresholdsProton proton collisionsQuantum interferenceStandard deviationMass spectrometersprotonadultarticlediagnosismass spectrometrynonhumanArticle10.1103/PhysRevLett.132.1119012-s2.0-85188184611
