Abstract

We present an update of a previous global analysis of the experimental data on azimuthal asymmetries in semiinclusive deep inelastic scattering (SIDIS), from the HERMES and COMPASS Collaborations, and in e+e -→ h1h2X processes, from the Belle Collaboration. Compared to the first extraction, a more precise determination of the Collins fragmentation function and the transversity distribution function for u and d quarks is obtained.
