Abstract

A new, preliminary global analysis of the experimental data on azimuthal asymmetries in SIDIS from HERMES and COMPASS collaborations, and in e ⁺e^- → h₁h₂X processes from the BELLE collaboration, is performed. The new data allow for a more precise determination of the Collins fragmentation function and of the transversity distribution function for u and d quarks, in comparison with the results of our previous analysis. Estimates for the single spin asymmetry A ^sin(φh+φS)_UT at JLab and COMPASS, operating on a transversely polarized proton target, are presented.
