Abstract

|
| Power-suppressed corrections to parton evolution may affect the theoretical accuracy of current determinations of parton distributions. We study the role of multigluon-exchange terms in the extraction of the gluon distribution for the large hadron collider (LHC). Working in the high-energy approximation, we analyze multigluon contributions in powers of 1/Q(2). We find a moderate, negative correction to the structure function's derivative dF(2)-/d 1n Q(2), characterized by a slow fall-off in the region of low to medium Q(2) relevant for determinations of the gluon at small momentum fractions.
