Transverse momentum dependent (TMD) factorization: status and progress — •Alexey Vladimirov — Regensburg University

The information on "3-dimensional imaging" of hadrons, encoded in unintegrated, transverse momentum dependent (TMD) parton densities and parton decay functions. At present it comes from two main sets of experimental data: low-qT Drell-Yan and semi-inclusive deep inelastic scattering (polarized and unpolarized). In each of these two cases, QCD factorization theorems allow one to relate observable cross sections to TMD parton distributions via perturbatively calculable kernels. We provide an overview of transverse momentum dependent (TMD) parton distribution functions and their application in high-energy physics phenomenology. The particular emphasis is made on the theoretical aspects TMD factorization, and on the recent development in this area.
