Energy Hadron

We deduce the particle distributions in particle collisions with multihadron-production in the framework of mechanical statistics. They are derived as functions of x, [Formula: see text] and the rest mass of different species for a fixed total number of all produced particles, inelasticity and total transverse energy. For PT larger than the mass of each particle, we have [Formula: see text] Values of <PT>π, <PT>K and [Formula: see text] in agreement with experiment are found by taking TH = 180 MeV (the Hagedorn temperature).

A continuous wavelet analysis is performed for pattern recognition of charged particle emission data in28Si-Ag/Br interaction at 14.5A GeV and in32S-Ag/Br interaction at 200A GeV. Making use of the event-wise local maxima present in the scalograms, we try to identify the collective behavior in multiparticle production, if there is any. For the first time, the wavelet results are compared with a model prediction based on the ultrarelativistic quantum molecular dynamics (UrQMD), where we adopt a charge reassignment algorithm to modify the UrQMD events to mimic the Bose-Einstein type of correlation among identical mesons—a feature known to be the most dominating factor responsible for local cluster formation. Statistically significant deviations between the experiment and the simulation are interpreted in terms of nontrivial dynamics of multiparticle production.

Energy Physics

Phenomenological models of multiparticle production have become increasingly important for the interpretation of experimental data in high energy physics. The evolution of these models fills a gap left open by the present limited theoretical understanding of the hadronization process, i.e. the transformation of outgoing colored partons into color singlet hadrons. The three main schools of thought, string fragmentation, cluster fragmentation and independent fragmentation, are presented in this paper. Included are discussions on similarities and differences, successes and failures, and recent developments. Perturbative QCD aspects with strong ties to the multiparticle production picture are also covered, in particular parton showers. An account is given of experience gained in the comparison between data and models. Since fragmentation studies are particularly well developed for e+e− annihilation events, this field is described in detail. A few comments are also presented for leptoproduction and hadron collisions.
