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 and 2000. Mini-jet multiplicities are presented as a function of the transverse momentum of the leading jet separately for two bins of the pseudorapidity of the leading jet and for three regions in the four momentum transfer squared Q2. The analysis is performed separately for the inclusive jet sample, and for a dijet sample, where the second jet is required to have an azimuthal angle larger than 140 degrees with respect to the leading jet. The dijet sample is split into two samples which are enhanced in direct photon and resolved photon processes, respectively. The results are compared to various QCD based models.
