I study hard collisions between unpolarized protons and antiprotons where alepton-antilepton pair is detected in coincidence with a finalproton-antiproton pair, and no more particles are produced, in the regime 10GeV^2 << s << 1000 GeV^2, M > 4 GeV, q_T < 3 GeV/c. The present work iscentered on azimuthal asymmetries. Because of momentum conservation, aBoer-Mulders term in the momentum distribution of a quark implies a balancingeffect in the momentum distribution of some spectators. This produces azimuthalasymmetries of the final hadrons. To analyze this, I have organized aparton-level MonteCarlo generator where a standard cos(2phi)-asymmetry of thedilepton distribution is produced, thanks to a soft rescattering processbetween an active quark coming from a hadron and a spectator anti-diquarkcoming from the other hadron. This produces cos(2phi)-asymmetries of the finalhadron pair. Hadron and lepton asymmetries have the same size.
