Résumé |
One of the central challenges in hadronic physics over the past decade has been to unravel the three-dimensional (3D) structure of the nucleon. A powerful tool for this task is provided by Transverse Momentum Distributions (TMDs), nonperturbative objects that encode the dependence of quarks and gluons on their longitudinal momentum fraction and their intrinsic transverse momentum relative to the parent hadron. By accessing TMDs through processes such as Drell–Yan lepton-pair production and semi-inclusive Deep Inelastic scattering, we can gain unprecedented insights into the quark and gluon dynamics that build nucleon structure.
In this seminar, I will discuss the current status of unpolarized TMD phenomenology and present the latest results from the MAP Collaboration on flavor dependence and on a new neural-network–based approach to TMD extractions. I will also show very recent progress on combining lattice-QCD calculations with experimental data to achieve a more precise determination of nonperturbative TMD evolution.
These advances are particularly relevant for future high-precision experiments such as the Electron–Ion Collider (EIC) and the high-luminosity LHC, where accurate control over TMD dynamics will be essential. |
