Abstract

We present results on J/ψ production in muon interactions with tin and carbon targets at incident muon energies of 200 and 280 GeV. The ratio of cross sections per nucleon for J/ψ production on tin and carbon, R(Sn/C), is studied as a function of p_T², z and x. We find an enhancement for coherent J/ψ production R_coh(Sn/C) = 1.54 ± 0.07, a suppression for quasielastic production R_qe(Sn/C) = 0.79 ± 0.06 and for inelastic production R_in(Sn/C) = 1.13 ± 0.08. The inelastic cross section ratio can be interpreted within the Colour Singlet model as an enhancement of the gluon distribution in tin with respect to that in carbon. The dependence of the ratio on z and p_T² can explain the discrepancy between the results obtained in previous experiments.
