Multiplicity Distribution studies of e+e−-annihilation at 50-61.4 and at 172-189 GeV by Two Stage Model hadronization
ثبت نشده
چکیده
The multiplicity distributions at high energy e+e− annihilation are described well within the Two Stage Model in the region from 14 to 189 GeV. Energy dependence of parameters of this model gives the dynamic picture of the parton stage and the stage of hadronization. It is shown that oscillations in sign of the ratio of factorial cumulant moments over factorial moments of increasing order can be confirmed by this model.

In this paper, we investigate the multiplicity of charged particles in e+ e– annihilation by using different models. To achieve this we first fit the multiplicity distribution of charged particles in the energy range of 54-57 GeV by using both the Poisson distribution and KNO scaling, then we compare these results with multiplicity distribution at the lower energies. This comparison shows that...
متن کاملKNO scaling in processes of electron - positron annihilation to hadrons
The charged particles multiplicity distribution in the KNO form is discussed in processes of ee annihilation at energies √ s 14 – 206.2 GeV. The experimental data are compared to data, obtained with Monte Carlo simulation in PYTHIA in the Lund quark string model. It is shown, that both experimental and simulated data are described by the same distribution function in the KNO form. It is shown, ...

Average values of< 1- T >where T is the thrust are presented for e: e: AMY data and are compared with their values in hadronic interactions. As far as possible, similar analysis techniques have been employed in the two different interactions. Similar variation with E is observed for this average in both data. The values of < PT> and < PL > relative to the thrust axis in e e are simila...

The gluon dominance model offers a description of multiparticle production in e + e −-annihilation and proton-proton collisions. The multiplicity distributions in e + e − annihilation are well described. The energy dependence of model parameters gives the dynamic parton stage and hadronisation picture. It is shown that this model has confirmed oscillations in sign of the ratio of factorial cumu...

We report on measurements of e+e~ annihilation into hadrons and lepton pairs. The data have been taken with the L3 detector at LEP at center-of-mass energies between 161 GeV and 172 GeV. In a data sample corresponding to 21.2 pb“" 1 of integrated luminosity 2728 hadronic and 868 lepton-pair events are selected. The measured cross sections and leptonic forward-backward asymmetries agree well wit...
