| Abstract: | Having studied the initial state energy loss versus nuclear shadowing for the Drell-Yan dimuon pair production in
the color string model, the inhomogeneous shadowing effect is
considered in this paper. We find that the inhomogeneous shadowing
effect does amend the rate of energy loss per unit path length, -dE/dz. Finally, the theoretical results for the Drell-Yan differential cross-section ratios are compared with the E772 and E866 data. It is found that the theoretical results are in good agreement with the experimental data. |
