Azimuthal Asymmetry of J/psi Suppression In Non-central Heavy-ion Collisions
The azimuthal asymmetry of J/{psi} suppression in non-central heavy-ion collisions is studied within a dynamic model of J/{psi} suppression in a deconfined partonic medium. Within this model, J/{psi} suppression in heavy-ion collisions is caused mainly by the initial state nuclear absorption and dissociation via gluon-J/{psi} scattering in deconfined partonic medium. Only the second mechanism gives arise to azimuthal asymmetry of the final J/{psi} production. We demonstrate that if there is an onset of suppression by quark-gluon plasma (QGP) in the NA50 data, it must be accompanied by the non-vanishing azimuthal asymmetry. Using the same critical density above which the QGP effect enters, we predict the azimuthal asymmetric coefficient {nu}{sub 2} as well as the survival probability for J/{psi} at the RHIC energy.
