Description
We discuss the elliptic and triangular flow of the J/ψ and the ψ(2S) in relativistic heavy ion collisions based on the coalescence model. Starting from the investigation of their production from the quark-gluon plasma by regeneration, we evaluate their anisotropic flow based on their yield distribution as functions of transverse momenta. We incorporate the transverse momentum distribution of charm quarks by combining the Tsallis distribution with the blast wave model to take into account the spatial dependence of the phase distribution. We show different elliptic and triangular flow for the J/ψ and ψ(2S), and argue that the wave function distribution of charmonium states plays a significant role, presenting plausible explanations for the measurements by the CMS Collaboration on elliptic flow of the J/ψ and ψ(2S).
