Abstract

A quantitative description of the qualitative feature of multihadron final states known as the "number of jets" is given by a sequence of infrared finite shape observables (jet discriminators) that take continuous values between 0 and 1, are stable—unlike clustering algorithms—against small variations of the input (data errors, Sudakov effects, etc.), and have a form of multiparticle correlators that is natural in the context of quantum field theory and hence are better suited for a systematic study of theoretical uncertainties (logarithmic and power correlations).
