Studying the effect of the hadronic phase in nuclear collisions with PYTHIA and UrQMD

Abstract

In this work, we couple Pb-Pb events simulated with the PYTHIA Angantyr event generator at $\sqrt{s_{\mathrm{NN}}}=2.76$ and $5.02$~TeV with the hadronic cascade simulator UrQMD to study the effect of the hadronic phase on observables such as charged-particle multiplicity densities, transverse momentum spectra and identified particle ratios, giving special emphasis to short-lived resonances.
