Hadron production in statistical model with vorticity

Abstract

Relativistic heavy ion collisions and the produced particle spectra supply essential information about the early universe and the states of nuclear matter. Using the statistical produc-tion model within the framework of some approximations, this study finds the chemical freeze-out conditions of temperature and baryochemical potential that origin a certain production of particles in such collisions. Then, the effect on the parameters of the model of a vortical component in the flow is verified. The inclusion of this magnitude indeed affects the parameters of this model, but in order for these changes to be substantial, thermal vorticity is required to take non physical values
