Observation of $J/\psi$ pair production in pp collisions at $\sqrt{s}=7 TeV$

Abstract : The production of $J/\psi$ pairs in proton-proton collisions at a centre-of-mass energy of 7 TeV has been observed using an integrated luminosity of $37.5 pb^{-1}$ collected with the LHCb detector. The production cross-section for pairs with both \jpsi in the rapidity range $2
