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 5σ and evid...
