Only a few of them have been given author entries in addition to the Collaboration. en dc.description.abstract We present first measurements of charged and neutral particle-flow correlations in pp collisions using the ATLAS calorimeters. Data were collected in 2009 and 2010 at centre-of-mass energies of 900 GeV and 7 TeV. Events were selected using a minimum-bias trigger which required a charged particle in scintillation counters on either side of the interaction point. Particle flows, sensitive to the underlying event, are measured using clusters of energy in the ATLAS calorimeters, taking advantage of their fine granularity. No Monte Carlo generator used in this analysis can accurately describe the measurements. The results are independent of those based on charged particles measured by the ATLAS tracking systems and can be used to constrain the parameters of Monte Carlo generators. en_US dc.language.iso eng eng dc.publisher Springer en_US dc.rights.uri http://www.springer.com/open+access/open+choice?SGWID=0-40359-0-0-0 eng dc.title Measurements of underlying-event properties using neutral and charged particles in pp collisions at √ s = 900 GeV and √ s = 7 TeV with the ATLAS detector at the LHC en_US dc.type Peer reviewed dc.type Journal article dc.description.version publishedVersion en_US dc.rights.holder ©The Author(s) 2011 en_US dc.identifier.doi https://doi.org/10.1140/epjc/s10052-011-1636-z dc.subject.nsi VDP::Mathematics and natural science: 400::Physics: 430 en_US dc.subject.nsi VDP::Mathematics and natural science: 400::Physics: 430::Nuclear and elementary particle physics: 431 en_US
