Omega, J/psi and psi' Transverse Mass Spectra at RHIC
The transverse mass spectra of J/psi and psi' mesons and Omega hyperons
produced in central Au+Au collisions at RHIC energies are discussed within a
statistical model used successfully for the interpretation of the SPS results.
The comparison of the presented model with the future RHIC data should serve as
a further crucial test of the hypothesis of statistical production of charmonia
at hadronization. Finally, in case of validity, the approach should allow to
estimate the mean transverse flow velocity at the quark gluon plasma
hadronization.Comment: revised version to appear in Phys. Lett.
Hadron Spectra and QGP Hadronization in Au+Au Collisions at RHIC
The transverse mass spectra of Omega hyperons and phi mesons measured
recently by STAR Collaboration in Au+Au collisions at sqrt(s_NN) = 130 GeV are
described within a hydrodynamic model of the quark gluon plasma expansion and
hadronization. The flow parameters at the plasma hadronization extracted by
fitting these data are used to predict the transverse mass spectra of J/psi and
psi' mesons.Comment: 4 pages, 4 figures, Fig. 3 correcte
