Descr. články - journal articles Language English Country United States of America Annotation Preliminary results on determination of the microscopic Hubble constant for pions and nucleons in Au + Au collisions at GeV for a range of times and fm are presented and discussed. The data are simulated within PHSD model. A typically used method based on the fit of the velocity profile is considered in detail. Also a new method for determination of the Hubble parameter is proposed. It consists in the analysis of the statistical distribution of the divergence of the velocity field and getting the Hubble parameter as a position of a particular peak of the distribution. A comparison of the methods is done. URL Link na plný text Link na plný text Public work category ADC No. of Archival Copy 54709 Catal.org.
