Abstract
The production of jets with low transverse momenta (mini-jets) in deep
inelastic electron-proton scattering is studied. The analyses uses data
taken with the H1 detector at HERA during the years 1999 to 2000. The
events are required to contain either at least one leading jet of Pt >
5 GeV (the inclusive 1-jet sample) or at least two hard jets where one of
them has to be at an angle larger than 140 degrees with respect to the
leading jet (inclusive 2-jet sample). Mini-jet multiplicities and their
average transverse momenta are presented as a function of Q^2, in two
regions of psuedo-rapidity and for two bins in the hadronic mass, W for
the inclusive 1-jet sample. For the inclusive 2-jet sample the results are
shown for direct and resolved photon interactions in two bins of W. The
results are compared to various QCD based models. A new method for
calibrating jet energy measurements up to 10 GeV has been developed and
its performance has been studied.
