Angular correlations in minimum bias events and other recent results in soft physics at D0 and ATLAS

Studies of minimum bias events at colliders and studies of the underlying event probe the behaviour of QCD in the non-perturbative regime. The phenomenology of events in this regime is described by empirical models that take many parameters that need to be tuned to the observed data. An overview of recent measurements from ATLAS in the soft regime will be given, with focus on the study of angular correlations between the highest transverse momentum charged particle track in an event and the others tracks in this event, performed at D0 and at ATLAS.

Time permitting, I will also discuss the search for the charged Higgs boson and in particular discuss how the “matrix element method” can play a role in this search at the Tevatron.
