The effective Lagrangian for the description of such a system is obtained after dropping the terms responsible for the change of the total particle number. Reactions π+π−↔π0π0, which deter-mine the isospin balance of the medium, are permitted. Within the self-consistent Hartree approximation we compute the effective pion mass, thermodynamic characteristics of the system and the variance of the particle number at temperatures above the critical point of the induced Bose–Einstein condensation when the pion chemical potential reaches the value of the effective pion mass. We analyze conditions for the con-densate formation in the process of thermalization of an initially non-equilibrium pion gas. The normalized variance of the particle number increases with a temperature decrease but remains finite in the critical point of the Bose–Einstein condensation. This is due to the non-perturbative account of the interaction and is in contrast to the ideal-gas case. In the kinetic regime of the condensate formation the variance is shown to stay finite also URL Link na plný text Kategória publikačnej činnosti ADC Číslo archívnej kópie 43902 Katal.org.

Vol. 830 (2009), pp. 195C-198C. - Amsterdam : Elsevier B.V., 2009 Kľúč.slová heavy ion collisions fluctuations Jazyk dok. angličtina Krajina Holandsko Anotácia We propose to use the Kolmogorov-Smirnov test to uncover non-statistical differences between events created in heavy ion collisions within the same centrality class. The advantage of the method over other approaches which are currently in use, is that it is sensitive to any difference between the events and is not restricted to simple moments of the distribution of hadrons. The particular application examined here is the identification of the fireball decay due to spinodal fragmentation and/or sudden rise of the bulk viscosity.

The phenomenon is due to large longitudinal dimensions of the space-time evolution of hadronic collisions and to the fact that the rapidity of a bremsstrahlung photon need not be close to the rapidity of the charged particle radiating the photon.
