Abstract:We present a phenomenological analysis of the $$q_{\text {T}}$$

-weighted transverse spin dependent azimuthal asymmetry recently measured by the COMPASS Collaboration in polarized pion-proton Drell–Yan process. In the kinematical regimes explored by experiments, we consider the leading-twist contributions from the Boer–Mulders distribution functions $$h_{1}^{\perp }(x,k_{\text {T}}^{2})$$
