Multiple Parton Interactions in Deep Inelastic ep-scattering at HERA

Osman, Sakar LU (2008)
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... (More)

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. (Less)
