【 摘 要 】

It is known that heavy quarks are produced in pairs. There always exists a correlation in azimuthal angle in transverse momentum plane between the members in a pair. The quark and anti-quark in a pair may lose different amount of energy while traveling through QGP and it is expected that the correlation of Q will alter considerably. Also in a complete different picture, collective flow of the medium can change the correlation of heavy quark pair. Here we present the effect of charm quark energy loss based on Wang-Huang-Sarcevic model on its correlation. The flow feature is shown using a naive model based on Cautle-Pa´ic model.
