dc.descriptionWhile presently available p-A data observe that the nuclear dependence of $J/ψ$ and $ψ^{\prime}$ production is the same within errors, we show that different nuclear dependence of $J/ψ$ and $ψ^{\prime}$ production in the kinematic region uncovered by the present p-A data can be predicted based on two different nuclear absorption scenarios. It is found that the predicted production ratio $σ(ψ^{\prime})/σ(J/ψ)$ at positive $x_F$ in A-p collisions is mainly determined by nuclear absorption, and hence allows direct experimental test of nuclear absorption scenarios.
