COLOR MIXING IN HIGH-ENERGY HADRON-COLLISIONS - ART. NO. 037501

The color mixing of mesons propagating in a nucleus is studied with th e help of a color-octet Pomeron partner present in the two-gluon model df the Pomeron. For a simple model with four meson-nucleon channels, color mixings are found to be absent for pointlike mesons and very sma ll fdr mesons of small sizes. These results seem to validate the absor ption model with two independent color components used in recent analy ses of the nuclear absorption of J/psi mesons produced in nuclear reac tions.
