Evidence for Statistical Production of J/ψ Mesons in Nuclear Collisions at 158–200 A GeV

The hypothesis of statistical production of J/psi mesons at hadronization is formulated and checked against experimental data. It explains in the natural way the observed scaling behavior of the J/psi to pion ratio at the CERN SPS energies. Using the multiplicities of J/psi and eta mesons the hadron...

description The hypothesis of statistical production of J/psi mesons at hadronization is formulated and checked against experimental data. It explains in the natural way the observed scaling behavior of the J/psi to pion ratio at the CERN SPS energies. Using the multiplicities of J/psi and eta mesons the hadronization temperature T_H=170 MeV is found, which agrees well with the previous estimates of the temperature parameter based on the analysis of the hadron yield systematics.
