Abstract: 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 5σ and evidence of an additional structure is reported with a local significance of 4.7σ.
