TMD Factorization in the hadron structure oriented approach

The main aspect of factorization relies on both the universality of the distributions as well as their interpretations as describing the internal structure of the hadrons. We present a novel approach, called Hadron Structure Oriented approach (HSO), which is best suited for hadron structure studies as it is built to both satisfy theoretic constrains originating from their operator definitions, as well as to clearly demarcate the perturbative contributions from the nonperturbative ones. Some practical examples in a Drell-Yan phenomenological analysis are studied which point the way toward the achievable improvements in future applications.
