Abstract

We investigate the impact of large-x resummation on parton distribution functions.We consider structure function data from the NuTeV, NMC and BCDMS experiments and extract NLO and NLL-resummed parton densities.Our analysis shows that soft resummation needs to be included for the sake of obtaining a precision level better than 10% at x 0 5 and moderate values of Q 2 .
