On the cos 2 phi asymmetry in unpolarized leptoproduction
Vincenzo Barone, Zhun Lu, Bo-Qiang Ma
We investigate the origin of the cos 2 phi azimuthal asymmetry in unpolarized semiinclusive DIS. The contributions to this asymmetry arising from the intrinsic transverse motion of…

Accessing transversity via J/Psi production in polarized p-pbar interactions
M. Anselmino, V. Barone, A. Drago +1
We discuss the possibility of a direct access to transversity distributions by measuring the double transverse spin asymmetry A_TT in p pbar --> J/Psi + X --> l^- l^+ + X processes…
