    "abstract": "We predict that initially produced chi_cJ mesons at low transverse momentum\nin the central rapidity region are almost dissociated by nucleons and\nantinucleons in hadronic matter produced in central Au+Au collisions at RHIC\nenergies sqrt {s_{NN}}= 130 and 200 GeV. In calculations the nucleon and\nantinucleon distributions in hadronic matter are results of evolution from\ntheir freeze-out distributions which well fit the experimental p_T spectra of\nproton and antiproton. Any measured chi_cJ mesons at low p_T are generated from\ndeconfined matter and give an explicit proof of regeneration mechanism\n(recombination mechanism).",
