New Structures in the J/ψ J/ψ Mass Spectrum at CMS
A search is reported for structures near the J/ψ J/ψ mass threshold using a dataset of proton-proton collisions at √ s = 13 TeV recorded with the CMS detector at the LHC, corresponding to an integrated luminosity of about 135 fb −1 . Two structures are observed with a significance exceeding 5 σ and...

| Zusammenfassung: | A search is reported for structures near the J/ψ J/ψ mass threshold using a dataset of proton-proton collisions at √ s = 13 TeV recorded with the CMS detector at the LHC, corresponding to an integrated luminosity of about 135 fb −1 . Two structures are observed with a significance exceeding 5 σ and evidence of an additional structure is reported with a local significance of 4.7 σ . |
