Abstract
We present some recently obtained results on transverse-momentum dependent parton distribution functions (TMD PDFs), the latter being important ingredients for the description of semi-inclusive hadronic processes. Special attention is payed to the renormalization group (RG) properties of these objects. In particular, their leading-order anomalous dimension is calculated in the light-cone gauge. It is shown that the RG properties can be used to reveal, in the most economic way, the general structure of the gauge links entering the operator definition of TMD PDFs.
