Baryonic Effect on chicJ Suppression in Au+Au Collisions at RHIC Energies

Original · EN

We predict that initially produced chicJ mesons at low transverse momentum in the central rapidity region are almost dissociated by nucleons and antinucleons in hadronic matter produced in central Au+Au collisions at RHIC energies sqrt sNN= 130 and 200 GeV. In calculations the nucleon and antinucleon distributions in hadronic matter are results of evolution from their freeze-out distributions which well fit the experimental pₜ spectra of proton and antiproton. Any measured chicJ mesons at low pₜ are generated from deconfined matter and give an explicit proof of regeneration mechanism (recombination mechanism).
