Dijet Production at HERA in Next-to-Leading Order

Abstract

Two-jet cross sections in deep inelastic scattering at HERA are calculated in next-to-leading order. The QCD corrections are implemented in a new $ep\to n$ jets event generator, MEPJET, which allows to analyze arbitrary jet definition schemes and general cuts in terms of parton 4-momenta. First results are presented for the JADE, the cone and the $k_T$ schemes. For the $W$-scheme, disagreement with previous results and large radiative corrections and recombination scheme dependencies are traced to a common origin.
