چکیده

The experimental results on the falling down of scaled factorial moments in azimuthal variable φ is studied in some detail. It is shown that this phenomenon may be referred to the influence of transverse momentum conservation. The existing experimental data from DELPHI, EMU08, NA22 and UA1 are successfully explained. Various methods are proposed to partly eliminate this influence and rule out the ’falling down’ of factorial moments. INSTITUTE OF PARTICLE PHYSICS HUAZHONG NORMAL UNIVERSITY WUHAN CHINA

Implementation of the Recovering Corrections into the Intermittent Data Analysis

The improved method of intermittent data analysis is proposed. It exploits, in addition to the standard density moments, the information on the bin-bin correlations, observed in the data and expressed in terms of the density correlators. The improving recovering corrections are implemented into the data analysis in the form of the recursive algorithm, and tested in the framework of multiplicati...

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...

Scaling and scale breaking phenomena in QCD jets

The perturbative QCD approach to multiparticle production assuming Local Parton Hadron Duality (LPHD) and some recent results are discussed. Finite asymptotic scaling limits are obtained for various observables, after an appropriate rescaling, in the Double Logarithmic Approximation (DLA). Nonasymptotic corrections are also known in some cases. The DLA applies also to very soft particle product...

Multiparticle Clusters and Intermittent Fluctuations

An approach for understanding the behaviour of multiplicity distributions in restricted phase-space intervals derived on the basis of global observables is proposed. We obtain a unifying connection between local multiparticle clusters and the scale-invariant power-law behaviour of normalized factorial moments. The model can be used to describe multiparticle processes in terms of a decomposition...

2 A comparison of different methods in the study of dynamical fluctuations in high energy e + e − collisions

A comparison of different methods in the study of dynamical fluctuations in high energy e + e − collisions ABSTRACT Different methods in the study of anomalous scaling of factorial moments in high energy e + e − collisions are examined in some detail. It is shown that the horizontal and vertical factorial moments are equivalent only when they are used in combination with the cummulant variables...
