Recent tests of parton hadron duality in multiparticle final states
Abstract
Description
A large variety of jet properties can be described perturbatively by evolving the parton cascade down to small scales of order of a few 100 MeV. We discuss two recent applications of this approach: 1. the soft limit of the particle spectrum which is nearly energy independent as expected for the soft gluon bremsstrahlung; further tests of this interpretation in $e^+e^-$ and DIS are presented; 2. the steep decrease of the distribution of rapidity gaps in $e^+e^-$ annihilation can be explained by the Sudakov formfactor for quark jets.
