N2 - New data from the BaBar Collaborations, on azimuthal correlations measured for pairs of pions produced in e+e- annihilations, are analysed together with analogous, previous data from the BELLE Collaboration and with Semi-Inclusive Deep Inelastic scattering (SIDIS) data, for a simultaneous extraction of transversity and the Collins function. Special attention is devoted to the p⊥ dependence of the Collins favoured and disfavoured functions. A comparison with BESIII new measurements allows a preliminary study on the sensitivity of azimuthal asymmetries on TMD evolution effects.
