The flow of heavy flavor in hydrodynamics
Abstract
The flow of charm is calculated in 2+1 ideal hydrodynamics by introducing the charge of cc pair assuming that the number of cc pairs is conserved in relativistic heavy-ion collisions. It is found that the mean radial flow velocity of charm quarks is smaller than that of bulk matter by 1015 \% and the measured v2 of heavy-flavor electrons is reproduced up to pTe= 1.5 GeV/c in Au+Au collision at RHIC. The same flow is applied to regenerated J/ and its v2 is discussed.
