Abstract：
J/ψ suppression in p-A collisions is studied by considering the nuclear effects on parton distribution, energy loss of beam proton and the finial state energy loss of color octet c c. The leading-order computations for J/ψ production cross-section ratios R _W/Be( x _F) are presented and compared with the selected E866 experimental data with the c cremaining colored on its entire path in the medium. It is shown that the combination of the different nuclear effects accounts quite well for the observed J/ψ suppression in the experimental data. It is found that the J/ψ suppression on R _W/Be( x _F) from the initial state nuclear effects is more important than that induced by the energy loss of color octet c cin the large x _Fregion. Whether the c cpair energy loss is linear or quadratic with the path length is not determined. The obtained c cpair energy loss per unit path length α=2.78±0.81 GeV/fm, which indicates that the heavy quark in cold nuclear matter can lose more energy compared to the outgoing light quark.
