Minijets and Transverse Energy Flow in High Energy Collisions

We study the distribution of jets and transverse energy flow in high energy hadron-hadron or nucleus-nucleus collisions. In the minijet region correlations and coherence effects can be taken into account in a description, where the parton flux is described by non-integrated structure functions. In a “naive” calculation based on integrated structure functions, the cross section blows up for small p⊥, which makes it necessary to introduce a soft cutoff. In our approach we find a dynamical suppression at low p⊥, which makes it possible to extrapolate to higher energies and make more reliable predictions for RHIC and LHC.
