[en] We report on the extraction of dihadron fragmentation functions (DiFF) from the semi- inclusive production of two hadron pairs in back-to-back jets in e+e− annihilation. A nonzero asymmetry in the correlation of azimuthal orientations of opposite π+π− pairs is related to the transverse polarization of fragmenting quarks through a significant polarized DiFF. A combined analysis of this asymmetry and the spin asymmetry in the SIDIS process ep↑ → e′(π+π−)X has led to the first extraction of the u and d-flavor transversity parton distribution function in the framework of collinear factorization.
