Observation of $\Upsilon(1S)$ pair production at CMS
The simultaneous production of two $\Upsilon(1S)$ mesons in proton-proton collisions is observed by CMS at $\sqrt s$ = 8 TeV at LHC in a data sample corresponding to an integrated luminosity of 20.7 fb$^{-1}$. The statistical significance is well in excess of 5 standard deviations. Both $\Upsilon$ c...
