Description
We analyse identified hadron spectra in transverse momentum with the
help of blast-wave model. Our approach properly includes all resonance
decays contributing to hadron production. It is shown that there is no
window in the transverse momentum where this contribution can be
safely neglected in order to use simpler analytical formulas in the
fit procedure. Based on the comparison of theoretical results to data
we identify the fiducial range for the fit. The fit is also performed
on Lambda's, Xi's and Omega's and the possibility of a different
freeze-out time for these species is discussed. The freeze-out
temperatures and transverse velocities for different centralities are
compared with previously published ALICE results and the values from
RHIC.
