Le résumé fourni par la source

Characteristics of multi-particle production in proton-proton collisions at √ s = 7 TeV are studied as a function of the charged-particle multiplicity, N ch .T h e produced particles are separated into two classes: those belonging to jets and those belonging to the underlying event.Charged particles are measured with pseudorapidity |η| < 2.4 and transverse momentum p T > 0.25 GeV/c.Jets are reconstructed from charged-particles only and required to have p T > 5G e V / c.The distributions of jet p T , average p T of charged particles belonging to the underlying event or to jets, jet rates, and jet shapes are presented as functions of N ch and compared to the predictions of the PYTHIA and HERWIG event generators.Predictions without multi-parton interactions fail completely to describe the N ch -dependence observed in the data.For increasing N ch , PYTHIA systematically predicts higher jet rates and harder p T spectra than seen in the data, whereas HERWIG shows the opposite trends.At the highest multiplicity, the datamodel agreement is worse for most observables, indicating the need for further tuning and/or new model ingredients.
