Description
Deep Inelastic Scattering at large Bjorken $x$ provides an interesting and unique framework to test modern factorization techniques. Although this topic has been widely discussed in the past within the context of effective theories, a consistent treatment in full QCD still faces issues regarding the treatment of rapidity divergences, subtractions, and the role played by soft radiation. In this talk, I will present a factorization theorem for DIS in the threshold region valid in full QCD addressing in detail the subtleties involved in the separation of the various contributions. I will also point out strong analogies and similarities between Transverse Momentum Dependent (TMD) factorization, offering a new appealing perspective that might open the path for a global study of hadronization effects involving different observables.
