    "abstract": "Using the perturbative method for the simulation of charmed particles, the\ndynamical origin of charm quark elliptic flow is studied in the framework of a\nmulti-phase transport (AMPT) model. Besides the expected ordering relative to\nthat of light quarks according to quark masses, charm quark elliptic flow is\nseen to be sensitive to the parton scattering cross section. To describe the\nobserved large elliptic flow of electrons from the decay of charmed mesons, a\ncharm quark elastic scattering cross section much larger than that estimated\nfrom the perturbative QCD is required.",
