Abstract

The amplitude of a 4-jet process ine + e − annihilation can be used to compute the associated flux of low energy particles due to the emission of soft gluons. I calculate the radiation pattern for the two contributing process,\(e^ + e^ - \to q\bar qgg\) and\(e^ + e^ - \to q\bar qq'\bar q'\), in a form suitable for comparison with the experimentally observed distribution of inter-jet hadrons. It is found that the dependence of the soft background radiation on the overall colour structure of the jet process can be used to differentiate between the two processes, and thus probe the 3-gluon coupling. I also suggest a suitable initial equation for extending the 4-parton cross-section to higher order gluon emission in a Monte Carlo parton shower algorithm and compare the spectrum so produced with results obtained on the parton level.
