Azimuthal asymmetries in unpolarized Drell-Yan processes and the Boer-Mulders distributions of antiquarks
Journal Article
·
· Physical Review D
Using a previous extraction of the quark Boer-Mulders distributions from semiinclusive deep inelastic scattering data, we fit the unpolarized Drell-Yan data on the $$\cos 2 \phi$$ asymmetry, determining the antiquark Boer-Mulders distributions. A good agreement with the data is found in the region of low $$q_T$$, where the transverse-momentum factorization approach applies.
