Description
In heavy-ion reactions, statistical models predict a rapid change in the baryon-to-meson ratio
as a function of the collision energy. This change occurs when the hadronic medium transits
from a baryon- to a meson-dominated gas. The transition is expected to take place at a
temperature of 140 MeV and a baryon chemical potential of 420 MeV, corresponding to a
collision energy of 8.2 GeV per nucleon in the center of mass. The Multi-Purpose Detector
(MPD), which is now under construction at the JINR, in Dubna, is designed to study heavy-ion
collisions at the energies from 4 to 11 GeV per nucleon. This energy range is suitable for the
exploration of this transition region. In this talk, we present results of feasibility studies for the
measurement of the transverse momentum spectra for mesons and baryons using Monte
Carlo simulated data samples, in order to explore the crossing point between these
transverse momenta as a function of the centrality and collision energy.
