Description

I will discuss recent work on the issues that arise when dealing with ultraviolet renormalization of both collinear and TMD Parton densities. In particulars, I will discuss how some commonly assumed properties like positivity can be violated in standard schemes. I will discuss the ways that using TMD parton densities can help even when dealing with collinear pdfs.
