Forward change distributions associated with hadronically produced J/psi particles

We have measured the forward charge as a function of xF of the psi for events produced by 225 Gev/c Tr-Be interactions. The forward charge is the average difference between the number of positive hadrons and negative hadrons produced in the forward hemisphere. The standard Drell-Yan model predicts that the forward charge should become less negative as the xF of the J/psi increases. The measured forward charge becomes more negative as the X, of the J/psi increases although it is consistent with being flat as a function of xF. Hence, the data is not consistent with any Drell-Yan type model which assumes the forward charge is not strongly dependent on the hadronic energy left over after the J/psi is formed.
