英文摘要In this paper, by means of the nuclear parton distribution obtained from the DGLAP equation, taking into account the energy loss of the beam proton through the nucleus, we analyze the QCD corrections to the measured Drell-Yan production cross sections for an 800GeV proton beam incident on Be, Fe and W nuclear targets in the Glauber model. For the nuclear parton distribution being extracted from the leading order, the results show that the QCD corrections can't improve the theoretical results fitting to the experimental data, especially in the cross section ratio of p-W to p-Be verse x(1). Then we calculate the Drell-Yan cross sections using the shadowing effect, which is extracted from the next-to-leading order by Frankfurt et al., and find that direct photon production should be sensitive to energy loss in Compton scattering and annihilation process.
