Hadron Multiplicities
We review results on hadron multiplicities in high energy particle collisions. Both theory and experiment are discussed. The general procedures used to describe particle multiplicity in Quantum Chromo-dynamics (QCD) are summarized. The QCD equations for the generating functions of the multiplicity distributions are presented both for fixed and running coupling strengths. The mean multiplicities...
متن کاملMultiplicities in Deep Hadron - Hadron Scattering
We derive, an expression for the average multiplicity for an inclusive experiment a + b +c + X, where a, b, and c are hadrons and c is detected with a large transverse momentum. If EC is the energy of c in the center-of-mass of aandb, wefind &/4, the last term is absent. C e+eand Ch are related to the av...
متن کاملHadron Multiplicities at HERMES
Hadron multiplicities of π − , π + , K − and K + have been measured in the deep-inelastic scattering of 27.5 GeV positrons off a hydrogen target. The data used in this analysis have been collected during the 2000 HERA running period. The multiplicities were obtained for 0.15< z <0.
متن کاملMultiplicities in Lepton - Hadron Processes
The average multiplicity at large w (w w s/Q2 + I) is Abstract in deep inelastic electro-and neutrinoproduction related in Feynman's version of the parton model to the average multiplicities in high-energy electron-positron annihilation and hadron-hadron scattering. The relation is: (n(s,Q2)'ep-Ce+e-Jn(Q2/$) + ChBn(o-1) VP where C e+e-and Ch are, respectively, the coefficients of en(s/Myi) in t...
متن کاملQcd Connection between Hadron and Jet Multiplicities 403: Qcd Connection between Hadron and Jet Multiplicities
The perturbative QCD provides a good overall description of both the jet and hadron multiplicities in the e + e − annihilation reaction. In this description the hadrons are considered as dual to partons at a small resolution parameter Q 0 characteristic of a hadronic scale of few hundred MeV. Abstract. The perturbative QCD provides a good overall description of both the jet and hadron multiplic...
