Description
After the conceptual improvements to transverse momentum dependent (TMD) extractions of a flavour dependent ansatz as well as a more robust propagation of uncertainties onto the resulting TMD functions in ART23, the following work ART25 is a state of the art determination of the unpolarised TMD parton distribution functions and -fragmentation functions such as the Collins-Soper kernel via a global fit on the available data.
With a simple model we reach a good result for the fit, overall describing the relevant phase space covered by semi-inclusive DIS and Drell-Yan experiments.
In my talk I want to review previous improvements, present our findings in this recent study, and comment on aspects on which this type of extractions can improve on.
