    "abstract": "Charm elliptic flow in heavy ion collisions at the Relativistic Heavy Ion\nCollider (RHIC) is studied in a multiphase transport model. Assuming that the\ncross section for charm quark scattering with other light quarks is the same as\nthat between light quarks, we find that both charm and light quark elliptic\nflows are sensitive to the value of the cross section. Compared to that of\nlight quarks, the elliptic flow of charm quarks is smaller at low transverse\nmomentum but approaches comparable values at high transverse momentum. Similar\nfeatures are seen in the elliptic flow of charmed mesons as well as that of the\nelectrons from their semileptonic decays when the charmed mesons are produced\nfrom quark coalescence during hadronization of the partonic matter. To describe\nthe large electron elliptic flow observed in available experimental data\nrequires a charm quark scattering cross section that is much larger than that\ngiven by the perturbative QCD.",
