Multiplicities 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 کاملParton Models and Deep Hadron - Hadron Scattering
We review the recent applications of various parton models, to the problem of hadron-hadron scattering at large momentum transfers. Models which allow direct parton-parton interactions as well as those that do not are considered. Predictions for the structure of hadronic final states (whether or not transverse jets exist), associated multiplicities, and the s and t dependencies of inclusive and...
متن کاملHadron 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 کاملdeep-inelastic lepton-hadron scattering
The most important part of the order α s corrections to the charm component of the charged-current structure functions F2(x,Q ) and F3(x,Q ) have been calculated. This calculation is based on the asymptotic form of the heavy-quark coefficient functions corresponding to the higher order corrections to the W-boson-gluon fusion process. These coefficient functions which are in principle only valid...
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.
