摘要：

We test the hypothesis that configurations of a proton with a large-x parton, x(p) greater than or similar to 0.1, have a smaller than average transverse size. The application of the QCD Q(2) evolution equations shows that these small configurations also have a significantly smaller interaction strength, which has observable consequences in proton-nucleus collisions. We perform a global analysis of jet production data in proton- and deuteronnucleus collisions at RHIC and the LHC. Using a model which takes a distribution of interaction strengths into account, we quantitatively extract the x(p) dependence of the average interaction strength, sigma(x(p)) thorn, over a wide kinematic range. By comparing the RHIC and LHC results, our analysis finds that the interaction strength for small configurations, while suppressed, grows faster with collision energy than does that for average configurations. We check that this energy dependence is consistent with the results of a method which, given sigma(x(p)) thorn at one energy, can be used to quantitatively predict that at another. This finding further suggests that at even lower energies, nucleons with a large-x(p) parton should interact much more weakly than those in an average configuration, a phenomenon in line with explanations of the EMC effect for large-x(p) quarks in nuclei based on color screening.
