Abstract

A study of the angular distributions of leptons from decays of J/ψ's produced in p-C and p-W collisions at sqrt{s}=41.6\mbox{∼GeV} has been performed in the J/ψ Feynman-x region -0.341 GeV/c a significant dependence on the reference frame is found: the polar anisotropy is more pronounced in the Collins-Soper frame and almost vanishes in the helicity frame, where, instead, a significant azimuthal anisotropy arises. © 2009 Springer-Verlag / Società Italiana di Fisica.
