Description
In recent years, significant progress has been made in understanding the 3D structure of the nucleon, driven by the development of TMD factorization. Although this framework has demonstrated strong predictive power, it still exhibits certain limitations that may be addressed by incorporating power corrections. By including kinematic power corrections (KPCs), we have successfully described the angular distributions of the Drell-Yan process, and we have found that these corrections play an even more prominent role in semi-inclusive deep inelastic scattering. Altogether, these findings suggest that current TMD distributions need to be updated: a new fit including KPCs is required to improve TMD extractions and, consequently, the tomographic picture of the nucleon.
