Measurement of double$~\mathrm{J}\hspace{-.08em}/\hspace{-.14em}\psi~$productions with the CMS detector

We present the new measurement of the cross section for the simultaneous production of two $~\mathrm{J}\hspace{-.08em}/\hspace{-.14em}\psi~$ mesons in proton-proton collisions at 7 TeV with the CMS detector. The two$~\mathrm{J}\hspace{-.08em}/\hspace{-.14em}\psi~$mesons are fully reconstructed in th...
