Abstract

By means of the nuclear parton distribution studied only with lepton deep-inelastic scattering experimental data, the effect of spatially inhomogeneous shadowing is studied in the p-A Drell–Yan dimuon production process. Using multiple soft rescattering theory, the initial state energy loss effect is also considered within the Glauber framework. The calculated results are compared to the E772 and E866 data. It is shown that the theoretical results while considering the energy loss effect are in good agreement with the experimental data. In this paper, we also compare the calculated results of inhomogeneous shadowing with those of homogeneous and find that the inhomogeneous shadowing results exhibit a stronger energy loss effect than the homogeneous results at the same parameter.
