Description

We study the pattern of soft parton radiation in the hard annihilation processes e+e- → qanti qγ and e+e- → qanti qg by explicit evaluation of the cross sections for e+e- → qanti qγg and e+e- → qanti qgg ue qanti qqanti q taken care of correct normalization. We find the coherence effects as observed experimentally and discuss why these effects are not present in the usual models based on O(αs2) perturbation theory with subsequent independent fragmentation.
