Non-extensive statistics in Au-Au collisions O. Costa, Juliana Aguiar, Isabelle L. Barauna, Jadna Megías Fernández, Eugenio Deppman, Airton N. da Silva, Tiago P. Menezes, Débora Heavy ion collisions Au-Au collision Non-extensive statistics Particle production yields measured in central Au-Au collision at RHIC are obtained with free Fermi and Bose gases and also with a replacement of these statistics by non-extensive statistics. For the latter calculation, a set of different parameters was used with values of the Tsallis parameter q chosen between 1.01 and 1.25, with 1.16 generating the best agreement with experimental data, an indication that non-extensive statistics may be one of the underlying features in heavy ion-collisions. 2024-09-11T09:15:33Z 2024-09-11T09:15:33Z 2024-05-21 journal article J.O.
