Measurement of inclusive jet production in deep inelastic scattering using ZEUS data — •Florian Lorkowski — DESY, Hamburg, Germany

The cross sections of deep inelastic scattering processes at electron-proton colliders are a well established tool to test perturbative QCD predictions. They can also be used to determine theory parameters, such as the strong coupling constant or the parton distribution functions of the proton.

In this talk, a measurement of inclusive jet cross sections in neutral current deep inelastic scattering using the ZEUS detector at the HERA collider is presented. The data was taken in the years 2003 to 2007 at a center of mass energy of 318 GeV and corresponds to an integrated luminosity of 372 pb−1. Massless jets, reconstructed using the k-algorithm in the Breit frame, are measured as a function of the squared momentum transfer Q2 and the transverse momentum of the jets in the Breit reference frame p⊥,Breit, in a range of 125 GeV2 < Q2 < 15000 GeV2 and p⊥,Breit > 7 GeV. The measured cross sections are compared to previous measurements.
