Blast-Wave Model Fit for Identified Particle Spectra and Elliptic Flow

Abstract

Blast-Wave Model is a model which has been used to describe the freeze-out con?guration in heavy-ion collisions. In this thesis, the results fitted from PbPb collisions at sNN = 2.76TeV are presented. Comparisons of the results based on different Blast-Wave Models as well as the discussion on the fitting parameters are discussed here. Considering the good agreements of experimental measurements and blast-wave calculations, we show the predictions from the blast-wave model with the parameters extracted from data.
