Measurement of the Underlying Event Activity at the LHC with $\sqrt{s}$= 7 TeV and Comparison with ~$\sqrt{s}$ = 0.9 TeV
First measurement of the underlying activity in proton-proton collisions at $\sqrt{s}$ =7 TeV compared with 900 GeV is presented, using data collected by the CMS experiment at the LHC in 2009/2010. The Multiple Parton Interaction rate, the main component of the Underlying Event activity, and its ene...
