Description
Some estimates for the transverse Single Spin Asymmetry, $A_N$,
in the inclusive processes $\ell \, p^{\uparrow} \to h \, X$ are compared with new experimental data. The predictions are based on the Sivers and Collins functions as extracted from SIDIS azimuthal asymmetries, within a transverse momentum dependent factorization approach. The values of $A_N$ thus obtained agree in sign and shape with the data.
