Title
Layout of Wilson lines and light-cone peculiarities of transverse-momentum dependent PDFs
Author
Abstract
We consider the problems of gauge invariance, path-dependence and treatment of overlapping UV/rapidity divergences peculiar to the transverse-momentum dependent parton distribution functions (TMDs). For different formulations of the TMDs available in the literature, we check the consistency of the TMD matrix elements with the collinear parton distribution functions pos- sessing the well-known operator structure. Comparative on- and off-light-cone layout of the Wil- son lines which secure the gauge-invariance of the TMDs is presented and briefly discussed.
