摘要
We study the correlation between the trigger π and the associated J/ψ on near and away sides in Au+Au collisions at sNN^(1/2) = 200 GeV. In the region of trigger momentum pt 〉 4 GeV/c, the π spectrum is composed of thermal-shower and shower-shower recombinations in the frame work of the recombination model. We consider the azimuthal anisotropy in the quenched hard parton distribution and then calculate the elliptic flow parameter v2 of charmed mesons (J/ψ, D0 and Ds) for different centralities.
