This is the development page for the TMD project. The purpose of this project is to organize a repository for theoretical and phenomenological studies of transverse-momentum-dependent parton distribution functions (TMD PDFs) and fragmentation functions (TMD FFs). We provde access to parametrizations and fits of TMDs, with and without taking into account the perturbative QCD evolution.
