| contents | We present a global analysis of Sivers functions, transversity distribution functions, and Collins fragmentation functions within the transverse momentum dependent factorization. This analysis encompasses the latest data from semi-inclusive deep inelastic scattering, Drell-Yan, and W/Z-boson production processes as recently reported by the COMPASS and STAR Collaborations. Upon integrating the new data into our fitting, the precision of the extracted d and dbar quark Sivers and transversity distributions, as well as the tensor charge, is notably improved. |
