  When studying the production of minijets and transverse energy flow in high
energy hadron-hadron or nucleus-nucleus collisions, two essential points have
to be taken into account. First, one has to account for the virtuality of the
colliding partons and secondly, it is important to avoid double counting, when
many links in a parton chain can be interpreted as the momentum transfer in a
hard subcollision. The Linked Dipole Chain model, introduced for low-x DIS, is
particularly suitable for a study of these problems. It describes (mini)jet
production in a kT-factorizing formalism, which includes all links in a parton
chain on an equal footing, avoiding double counting. In a ``naive'' calculation
based on integrated structure functions, the cross section blows up for small
pT, which makes it necessary to introduce a soft cutoff. In our approach we
find a dynamical suppression at low pT, which makes it possible to extrapolate
to higher energies and make more reliable predictions for RHIC and LHC.
