At the leading twist, the transversity distribution function, h^{q}_{1}(x)h1q(x), where xx is the longitudinal momentum fraction of the proton carried by quark qq, encodes the transverse spin structure of the nucleon. Extraction of it is difficult because of its chiral-odd nature. In transversely polarized proton-proton collisions (p^\uparrow pp↑p), h_{1}^{q}(x)h1q(x) can be coupled with another chiral-odd partner, a spin-dependent fragmentation function (FF). The resulting asymmetries in hadron(s) azimuthal correlations directly probe h_{1}^{q}(x)h1q(x). We report the measurement of correlation asymmetries for charged pion(s) in p^\uparrow pp↑p, through the Collins and the Interference FF channel.
