Transverse Momentum Distribution as a Probe of J/psi Production Mechanism in Heavy Ion Collisions
Abstract
We investigate J/psi transverse momentum distribution in a transport approach. While the nuclear modification factor RAA(Np) at RHIC is almost the same as at SPS, the averaged transverse momentum square <pt2> and RAA(pt) are very different at SPS, RHIC and LHC and can be used to differentiate from the J/psi production mechanisms in high energy nuclear collisions.
