Jet Production and Parton Dynamics in Deep Inelastic Scattering

Mattias Davidsson

Research output: ThesisDoctoral Thesis (monograph)


Hard QCD processes have been studied by measuring the di-jet event rate for deep inelastic scattering in the kinematic range 5 < Q<sup>2</sup> < 100 GeV<sup>2</sup> and 10<sup>-4</sup> < x < 10<sup>-2</sup>. The jets we re reconstructed using the cone algorithm in the hadronic center-of-mass frame in which the transverse momentum of the jets were required to be greater than 5 GeV. The result of the investigation is that using Leading Order QCD calculations together with pure DGLAP parton showering we can not reproduce the relative rate of hard di-jet events in DIS. To accomplish this the transverse momentum ordering in the parton ladder has to be broken as can be achieved by the inclusion of a component which resolves the photon in the DGLAP picture, or by using the Color Dipole Model for the higher order QCD radiation.
