A novel approach to TMD physics and phenomenology focused on hadronic structure

Factorization theorems involving Transverse Momentum Distributions (TMDs) provide a powerful tool for exploring the three-dimensional structure of hadrons. While the theoretical framework for these theorems and their scale evolution is well-established, consistently connecting the factorized expressions for processes like Semi-Inclusive Deep Inelastic Scattering (SIDIS) and Drell-Yan has proven challenging. This difficulty stems from the intricate relationship between TMDs and their collinear counterparts, which are linked through integral relations. We demonstrate how to achieve a comprehensive TMD factorization and evolution while retaining a parton-model-like picture. Our approach ensures a clear separation between perturbative and nonperturbative contributions, while rigorously adhering to the theoretical constraints imposed by the operator definitions of TMD distributions. A practical application of this approach is provided for Drell-Yan-like processes, including lepton pair production at moderate Q2Q^2 and Z0Z^0 boson production, offering a clearer understanding of the phenomenology and reducing the reliance on arbitrary auxiliary parameters that can distort expected physical behavior.
