Abstract
We show that the polarized proton-antiproton Drell-Yan process is ideal to probe the pretzelosity distribution (), which is one of the new transverse-momentum-dependent parton distributions of the nucleon. We present predictions of the asymmetry in the transversely polarized proton-antiproton Drell-Yan process at PAX kinematics and find that the results are significantly larger compared with those of the asymmetry in the semi-inclusive deep inelastic scattering process at HERMES, COMPASS, and JLab kinematics. We conclude that the asymmetry in the PAX experiment can probe the new physical quantity of the pretzelosity distribution.
