Description

We compute resonance (rho, K*(892), phi(1020), f2'(1252), Lambda(1520), Sigma(1775)) yields and spectra in PbPb collisions at 5.02 TeV using hydrodynamics with hadronic afterburner. The yields and <pT> agree with available experimental data. With the afterburner the yields are substantially suppressed and the mean transverse momenta are substantially enhanced compared to the case without afterburner. The only exception of this rule is phi(1020), which remains unaltered by the afterburner. First, we provide a simple qualitative explanation of this phenomenon. Second, the available measurements of Lambda(1520) by ALICE allow us to estimate the duration of hadronic rescattering stage after hadronization of the quark-gluon plasma.
