Title:     Early physics with the ATLAS detector: measuring minimum bias and the underlying event

Abstract: High-energy hadron collisions are a combination of soft and hard processes. Although perturbative QCD is successful in describing hard partonic interactions it cannot be applied to soft processes. Alternative approaches are therefore required to describe the
soft component of hadron collisions. In this seminar I will review ATLAS studies on Monte Carlo generators (e.g. PYTHIA, HERWIG
and PHOJET) used to describe soft interactions in hadron-hadron collisions.  Based on a wide range of minimum bias and underlying
event measurements I will discuss how effective these models are in describing the data, and how reliable are their predictions to the LHC. I will also give an update on the preparations to measure minimum bias and the underlying event associated to jet production at ATLAS.

Stimulants available 15 minutes before the talk.
