Global fit of TMD distributions: ART25

Résumé fourni par la source

This study is a recent determination of transverse momentum dependent parton distribution functions, fragmentation functions such as the Collins-Soper kernel. The extraction is based on a global analysis of measurements of the Drell-Yan and the semi-inclusive deeply inelastic scattering processes. The work labeled as ART25 provides a good description of the small transverse momentum spectrum of the data, is in general agreement with prior studies and incorporates technical improvements such as a flavour dependent parametrisation of the fragmentation functions and a large-𝑥 resummation for the coefficient functions connecting the distributions to their collinear counterparts.
