Test of Qcd Predictions for Multiparticle Production at Lep
نویسنده
چکیده
The constants b and c entering in this expression can be calculated, and especially in the result for c enters crucially the assumption of coherence: neglecting the effect of angular ordering would increase it by a factor of √ 2. The data up to the highest energies keep to be in fair agreement with this prediction 1 (see Fig.1). An important point in this measurement is that the LEP data have been corrected for the different b quark fractions. The ratio of mean and dispersion is predicted to have a very mild energy dependence, or even to be energy independent according to the KNO scaling property. Also these predictions are met by the data within errors.

Density Uctuations in Multiparticle Production at High Energies
Besides being important to describe high energy processes themselves, the dynamics of multiparticle production is part of the general eld of non-linear phenomena and complex systems. Multiparticle dynamics is one of the rare elds of physics where higher order correlations are directly accessible in their full multi-dimensional characteristics under well controlled experimental conditions. This ...
متن کاملTWO TOPICS IN MULTIPARTICLE DYNAMICS AT LEP: MULTIPLICITY IN bb̄ EVENTS AND SCREWINESS AT THE END OF THE QCD CASCADE
This talk deals with two topics in multiparticle dynamics investigated by means of the DELPHI detector at LEP. Related to the first topic, we have used the data collected at 183 GeV to measure the average charged particle multiplicity in e+e− → bb̄ events. The result is remarkably in agreement with QCD predictions, while it is more than two standard deviations larger than calculations assuming t...
متن کاملPROPERTIES OF THE Z ! b
The decays of the Z into b b pairs are a unique laboratory for the study of QCD and multiparticle production models. In this report, after a short review on the techniques for the selection of such events, a summary is given of the experimental results on production of charged particles and of identiied-nal states in b b events and in the decays of b hadrons at LEP, b fragmentation, and tests o...
متن کاملReview of Theory Talks at Xxix International Symposium on Multiparticle Dynamics
The main trend in theoretical applications of QCD to processes of multiparticle production during recent years, which was well presented at this Symposium, can be summarised as: ”From small to large distances or an interplay of perturbative and nonperturbative aspects of QCD”. The basis of QCD is rather well established now by a comparison of its predictions with experiments sensitive to small ...
متن کاملMultiparticle Production and Perturbative Qcd
The perturbative quantum chromodynamics (QCD) is quite successful in the description of main features of multiparticle production processes. Ten most appealing characteristics are described in this brief review talk and compared with QCD predictions. The general perturbative QCD approach is demonstrated and its problems are discussed. It is shown that the analytical calculations at the parton l...
