Quantum Clan Model description of Bose Einstein Correlations

We propose a novel numerical method of modelling Bose-Einstein correlations (BEC) observed among identical (bosonic) particles produced in multiparticle production reactions. We argue that the most natural approach is to work directly in the momentum space in which the Bose statistics of secondaries reveals itself in their tendency to bunch in a specific way in the available phase space. Because such procedure is essentially identical to the clan model of multiparticle distributions proposed some time ago, therefore we call it the Quantum Clan Model.Comment: Talk given at 4th Budapest Winter School On Eavy Ion Physics (2004), 6 pages, two figures; version published in APH (HIP

Multiparticle production processes from the Information Theory point of view

We look at multiparticle production processes from the Information Theory point of view, both in its extensive and nonextensive versions. Examples of both symmetric (like pp or AA) and asymmetric (like pA) collisions are considered showing that some ways of description of experimental data used in the literature are of more general validity than usually anticipated.}Comment: Talk given at 4th Budapest Winter School On Heavy Ion Physics (2004) 16 pages, 5 figures; version published in APH (HIP

Numerical symmetrization of state of identical particles

The method of numerical symmetrization of state of identical particles proposed by us before is clarified and discussed.Comment: Talk presented by O.Utyuzh at XXXVI International Symposium on Multiparticle Dynamics, September 2-8, 2006, Paraty (RJ), Brazil; minor corrections, to be published in Braz.
