Quarkonium polarization in pp and p-nucleus collisions
The existing measurements of quarkonium polarization in proton-antiproton and proton-nucleus collisions are puzzling. We highlight issues which are often underestimated in the experimental analyses: the importance of the choice of the reference frame, the interplay between observed decay and product...
