The jet definition scheme is based on a modified JADE cluster algorithm.

WebCorrections beyond the leading order of perturbative QCD are computed for the evolution of jets and scaling violation in the parton fragmentation functions. We present the prescription for calculating the jet calculus vertices to higher orders, and give complete results for the quark decay probabilities in the next-to-leading approximation.
