Color gauge invariance in hard processes

F. Pijlman

    Research output: Contribution to JournalArticleAcademicpeer-review


    Within the theoretical framework which we apply, a suggested origin for single-spin asymmetries is the presence of gauge links in transverse momentum-dependent distribution functions. Recently we found new gauge-link structures in a number of hard processes. These structures need to be considered in the evolution of parton distribution functions and for establishing factorization.
