Observation of triple $\mathrm{J}\mspace{-2mu}/\mspace{-2mu}\psi$ meson production in proton-proton collisions at $\sqrt{s} = 13~\mathrm{TeV}$
The first observation of the combined production of three $\mathrm{J}\mspace{-2mu}/\mspace{-2mu}\psi$ mesons in proton-proton collisions at a center-of-mass energy of $13\,\mathrm{TeV}$ is reported. The analysis is based on a data sample recorded by the CMS experiment at the CERN LHC corresponding t...
