We gauge the impact of soft-gluon resummation on quark distributions by performing a simple fit of deep inelastic scattering structure function data using next-to-leading order (NLO) and next-to-leading-logarithmic- (NLL)-resummed coefficient functions. We make use of NuTeV charged-current data, as well as New Muon Collaboration (NMC) and Bologna-CERN-Dubna-Munich-Saclay (BCDMS) neutral-current results, which probe large values of x. Our results suggest that the inclusion of resummation effects in global fits of parton distributions is both feasible and desirable, in order to achieve at large x the accuracy goals of the LHC physics program.
