QCD Jets at HERA II.O(α 2s ) four-jet cross-sections

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

We present exact expressions for theO(α 2s ) tree graph four-jet cross-sections in neutral current and charged current deep inelasticep scattering initiated by quarks, antiquarks and gluons including lepton polarization effects. Using helicity amplitudes the partonic cross-sections are given in concise form including all colour, flavour and statistical factors. We explicate the electroweak coupling dependence and state how the partonic cross-sections are folded with the respective parton densities to obtain theep jet cross-sections toO(α 2s ). We present some numerical results for the neutral current one-photon exchange case. We elaborate on the cut dependence of the jet rates and present differential distributions in some basic kinematical variables.
