An analysis of 4 % of these data has allowed to extract preliminary results on the amplitudes of three azimuthal modulations, $A_{UU}^{\\cos\\phi_h}$, $A_{UU}^{\\cos2\\phi_h}$ and $A_{LU}^{\\sin\\phi_h}$. The first two are particularly important since they carry information on the intrinsic transverse momentum $\\vec{k}_T$ of the quarks and on the correlations between the quark spin and $\\vec{k}_T$, expressed by the Boer-Mulders TMD PDFs.
