Résumé |
Extracting information on fundamental QCD operators from hadronic cross sections is challenging, mainly due to the important role of non-perturbative effects at low energy scales. With the increasing precision of upcoming measurements, it becomes essential to establish a clearer connection between formal factorization and phenomenological approaches. In this seminar, I will discuss the phenomenology of transverse-momentum-dependent (TMD) parton distributions, and present a novel framework based on analytic resummation. This approach relates the non-perturbative structure of TMDs to fundamental QCD properties, such as the infrared behavior of the strong coupling and collinear parton distributions. I will also show how processes that are seemingly unrelated share common underlying universal features. Making these connections explicit opens the possibility of unifying different frameworks, ultimately enhancing the predictive power for precision QCD observables. |
