Observation of an excess of di-charmonium events in the four-muon final state with the ATLAS detector
A search for potential $cc\bar{c}\bar{c}$ tetraquarks decaying into a pair of charmonium states in the four muon final state is performed using proton-proton collision data at $\sqrt{s}=13$ TeV, corresponding to an integrated luminosity of 139 fb$^{-1}$ recorded by the ATLAS experiment at the Large...
