Double transverse-spin asymmetries in Drell--Yan and $J/\psi$ production from proton--antiproton collisions

V. Barone, C. Coriano A. Cafarella, M. Guzzi +1

We perform a NLO numerical study of the double transverse-spin asymmetries in the $J/\psi$ resonance region for proton--antiproton collisions. We analyze the large $x$ kinematic regio…
