Pion, Kaon and Proton (Anti-proton) production in Au+Au collisions at
\sqrt(s_NN) = 62.4 GeV

In 200 GeV Au+Au collisions at RHIC, a scaling according to the
number of constituent quarks in a hadron seems to govern the particle
production and elliptic flow at intermediate p T . This observation can
be explained by coalescence of constituent quarks at hadronization
from a collective partonic system. We extend our study of this
mechanism and the bulk properties at lower energies from the recent
62.4 GeV Au+Au collisions at RHIC. Particle identification at low
and intermediate pT is from Time Projection Chamber and Time­
of­ Flight system at STAR. In this talk, we will present the spectra
and nuclear modification factor of Pion, Kaon and Proton (Anti-Proton)
production as a function of the collision centrality and transverse
momentum. Model comparison with coalescence approach results will be made.
