Resumen:
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.
