Minimum bias and underlying event studies at CMS

The Underlying Event (UE) at CMS is studied by examining charged particle and momentum densities in the transverse region in charged particle jet production. The predictions of various QCD models with different multiple parton interaction schemes correctly reproduce Tevatron data, however they fail...

description The Underlying Event (UE) at CMS is studied by examining charged particle and momentum densities in the transverse region in charged particle jet production. The predictions of various QCD models with different multiple parton interaction schemes correctly reproduce Tevatron data, however they fail to agree with each other when extrapolated to the LHC energy. The possibility of discriminating among these models is presented. Exploring QCD dynamics in proton-proton collisions at center-of-mass energy of 14 TeV, and the importance of improving and tuning the QCD Monte Carlo models at start-up are also analyzed.
