Abstract

The mean squared transverse momentum of J/ψ's measured in pCu, pU, OCu, OU and SU collisions at 200 GeV/ nucleon is analyzed in terms of initial state interactions. Taking this effect into account, the mechanism which suppresses the J/ψ production in ion-induced collisions would only have a weak PT dependence.
