Observation of double $J/\psi$ production in proton-proton collisions at a centre-of-mass energy of $\sqrt{s}$ = 7 TeV
The production of $J/\psi J/\psi$~pairs in proton-proton collisions at a centre-of-mass energy of $\sqrt{\mathrm{s}}=7~\mathrm{TeV}$ has been observed with the LHCb detector with an integrated luminosity of $35.2~\mathrm{pb}^{-1}$. The production cross section for $J/\psi J/\psi$~pairs with both $J/...
