N2 - Using a previous extraction of the quark Boer-Mulders distributions from semi-inclusive deep inelastic scattering data, we fit the unpolarized Drell-Yan data on the cos2 asymmetry, determining the antiquark Boer-Mulders distributions. A good agreement with the data is found in the region of low qT, where the transverse-momentum factorization approach applies.
