$J/\psi$ production and elliptic flow parameter $v_2$ at LHC energy

Abstract

We apply the recombination model to study $J/\psi$ production and its elliptic flow in the region of $10<p_T<20$ GeV/$c$ at LHC energy. We show the distribution of $J/\psi$ as function of the transverse momentum $p_T$ and the azimuthal angle $\varphi$. If the contribution from the recombination of shower partons from two neighboring jets can not be ignored due to the high jet density at LHC, the elliptic flow parameter $v_2$ of $J/\psi$ is predicted to decrease with $p_T$.
