Study of psi' and chi_c decays as feed-down sources of J/psi hadro-production
read the original abstract
The interpretation of the J/psi suppression patterns observed in nuclear collisions, at CERN and RHIC, as a signature of the formation of a deconfined phase of QCD matter, requires knowing which fractions of the measured J/psi yields, in pp collisions, are due to decays of heavier charmonium states. From a detailed analysis of the available mid-rapidity charmonium hadro-production cross sections, or their ratios, we determine that the J/psi feed-down contributions from psi' and chi_c decays are, respectively, (8.1 +/- 0.3) % and (25 +/- 5) %. These proton-proton values are derived from global averages of the proton-nucleus measurements, assuming that the charmonium states are exponentially absorbed with the length of matter they traverse in the nuclear targets.

Absorption of 1$P$-wave heavy charmonium $\chi_{c1}(1P)$ in nuclei
Calculations of excitation functions, momentum spectra, and transparency ratios for χ_c1(1P) on 12C and 184W nuclei demonstrate sensitivity to different absorption cross-section scenarios, proposed for extraction via ...
