A solution to the problem of the identification of an arbitrary number of jets in high energy collisions is reviewed.1Some of the applications of this solution to the study of the Electroweak Interactions are illustrated through two examples: The detection and analysis of top quarks, and the detection of charged Higgs or Pseudo Goldstone bosons, in e+e−reactions. Although these two examples involve e+e−initial states, the jet identification method described in this paper could be used in the analysis of any reaction involving jets.
