$J/Psi$ suppression in nuclear collisions at SPS energies | | W. Cassing

10 Sep 1996 | | Journal: | Phys.Lett. B396 (1997) 39-44 | | Subject: | nucl-th | | Affiliation: | Giessen Univ.) and C.M. Ko (Texas A&M Univ. | | Abstract: | We have carried out a first calculation of $J/Psi$ production from nuclear collisions within the covariant transport approach HSD, which has been very successful in describing both hadronic and electromagnetic observables from heavy-ion collisions at intermediate and high energies. The production of $J/Psi$’s is based on the Lund string fragmentation model, while its interactions with hadrons are included by conventional cascade-type two-body collisions. Adopting 6 mb for the $J/Psi$-baryon cross sections and 3 mb for the $J/Psi$-meson cross sections above the $Dar{D}$ threshold, we find that data on $J/Psi$ suppression from both proton-nucleus and nucleus-nucleus collisions (including Pb + Pb) can be explained without assuming the formation of a quark-gluon plasma in these collisions. Our microscopic studies thus confirm the suggestion of Gavin et al. that $J/Psi$ suppression observed in nuclear collisions is largely due to absorption by comovers, i.e., the produced mesons. | | Source: | arXiv, nucl-th/9609025 | | Services: | Forum | Review | PDF | Favorites | |
