NLO QCD calculations in DIS at HERA based on the dipole formalism∗

We briefly describe a new general algorithm for carrying out QCD calculations to next-to-leading order in perturbation theory. The algorithm can be used for computing arbitrary jet cross sections in arbitrary processes and can be straightforwardly implemented in general-purpose Monte Carlo programs. We show numerical results for the specific case of jet cross sections in deep inelastic scattering at HERA energies. CERN-TH/96-240 September 1996 ∗Presented by M.H.
