Description
We present a global re-analysis of the experimental data on azimuthal asymmetries in semi-inclusive deep inelastic scattering (SIDIS), from the HERMES and COMPASS Collaborations, and in e^+ e^- to h1 h2 X processes, from the Belle Collaboration. Transversity and Collins functions are extracted simultaneously, in the framework of a new and revised global analysis in which a new parameterization of the unknown functions will be tested.
