Production of Strange and Charm Hadrons in Pb plus Pb Collisions at vsNN=5.02 TeV

摘要

Using a quark combination model with the equal-velocity combination approximation, we study the production of hadrons with strangeness and charm flavor quantum numbers in Pb+Pb collisions at root sNN= 5.02 TeV. We present analytical expressions and numerical results for these hadrons' transverse momentum spectra and yield ratios. Our numerical results agree well with the experimental data available. The features of strange and charm hadron production in the quark-gluon plasma at the early stage of heavy ion collisions are also discussed.
