Model for J/ absorption in hadronic matter Academic Article uri icon


  • The cross sections for J/ absorption by and mesons are studied in a meson-exchange model that includes not only pseudoscalar-pseudoscalar-vector-meson couplings but also three-vector-meson and four-point couplings. We find that they are much larger than in a previous study where only pseudoscalar-pseudoscalar-vector-meson couplings were considered. Including form factors at interaction vertices, the J/ absorption cross sections and are found to have values on the order of 7 mb and 3 mb, respectively. Their thermal averages in hadronic matter at temperature T = 150 MeV are, respectively, about 1 mb and 2 mb.
