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

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 sc...
