Abstract
A detailed study ofJ/ψ hadronic production has been performed in a high statistics experiment (more than 1.5 106 J/ψ observed in their dimuon decay mode). Data have been taken with incident π±,K ±,p ±, on hydrogen and platinum targets, at 150, 200 and 280 GeV/c. We find from the observed nuclear dependance of the cross sections, that about 18% of theJ/ψ are produced diffractively. Using known structure functions of the quarks in the nucleon and in the pion, we derive estimations for the gluon structure functions.
