Description

The TMD factorization at the next-to-leading power has an involved structure of singularities. I discuss the definition and properties of transverse momentum dependent (TMD) distributions of the twist-three including evolution, symmetry relations, parametrization, interpretation, and singularities. I demonstrate that the physical TMD distributions (in terms of which observables are written) require an extra subtraction procedure. As an example of application, I discuss the Drell-Yan hadronic tensor at the next-to-leading power in terms of physical distributions and explicitly demonstrate the cancellation of rapidity and end-point divergences. These results complete the construction of TMD factorization at the next-to-leading power.
