Description
we present a global analysis of Sivers function, transversity distribution functions and Collins fragmentation func-
tions within TMD factorization. This analysis encompasses the latest data sets from semi-inclusive deep inelastic scattering, Drell-
Yan, and W±/Z-boson production as recently reported by the COMPASS and STAR Collaborations. Upon integrating this new data
into our fitting, the accuracy of the d and ¯d quark extraction for both transversity and Sivers distribution is notably improved.
