Measurement of distributions sensitive to the underlying event in inclusive Z-boson production in pp collisions at s = 7 TeV with the ATLAS detector

Popis výsledku v původním jazyce

A measurement of charged-particle distributions sensitive to the properties of the underlying event is presented for an inclusive sample of events containing a Z -boson, decaying to an electron or muon pair. The measurement is based on data collected using the ATLAS detector at the LHC in proton?proton collisions at a centre-of-mass energy of 7 TeV with an integrated luminosity of 4.6 fb1 . Distributions of the charged particle multiplicity and of the charged particle transverse momentum are measured inregions of azimuthal angle defined with respect to the Z -boson direction. The measured distributions are compared to similar distributions measured in jet events, and to the predictions of various Monte Carlo generators implementing different underlying event models.
