Abstract

We derive the angular correlation functions between an arbitary number of partons inside a quark or gluon jet emerging from a high energy hard collision. As an application results for the correlation in the relative angle between two partons as well as the multiplicity moments of any order for partons in a sidewise angular region are calculated. At asymptotic energies the distributions of rescaled angular variables approach a scaling limit of a new type with two redundant quantities. All observables reveal the power behaviour characteristic to the fully developed selfsimilar cascade in appropriate regions of phase space. We present analytical results from the double logarithmic approximation as well as Monte Carlo results.
