A measurement of J/psi polarization has been performed for 200 GeV proton+proton collisions with the PHENIX Muon Arms at RHIC. The results from the current data show no polarization within the PHENIX acceptance range. The results are consistent with the current model predictions and other experimental measurements.;Index words. RHIC, PHENIX, Proton+proton collisions, J/psi, Polarization 200 GeV... |
