Double-J/ψ system in the spotlight of recent LHCb data

Double-J/ψ system in the spotlight of recent LHCb data

Recently the LHCb Collaboration announced intriguing results on the double-$J/\psi$ production in proton-proton collisions. A coupled-channel interpretation of the measured di-$J/\psi$ spectrum is presented and a possible nature of the proposed near-threshold state $X(6200)$ is discussed.
