The method is based on the analytical formulas, that were earlier successfully utilized in the studies of Pb+Pb collisions at sNN=2.76 TeV. To test the method, the spectra, radii and particle radiation picture are calculated within the integrated hydrokinetic model. Thus, the fitting results for maximal emission times of kaons and pions are compared to the approximate maximal emission time values, estimated based on the emission function plots. The developed simple method was successfully applied to the data analysis in the case of lower LHC energy. Two-boson momentum correlations at fixed particle number constraint are studied in a simple analytically solvable model of a thermal expanding system. We show that the increase of expansion rate, as well as increase of particle multiplicity, lead to suppression of the Bose-Einstein momentum correlations due to partial coherence of the ground-state contribution to particle momentum spectra Product Description popup.authors Adzhimambetov Musfer D Akkelin Sergii V.
