O ct 2 00 5 PHENIX Results on Open Heavy Flavor Production and Flow in Au + Au Collisions at √ s NN = 200 GeV

Abstract

Interaction of heavy quarks with hot dense matter, created in heavy ion collisions at RHIC, is a very important probe for understanding the properties of the produced medium. For the case of the light quark, the strong suppression of high transverse momentum pions has been experimentally measured [ 1, 2]. This important result implies that hard scattered partons traveling through the medium created in such collisions experience considerable energy loss. The same effect for heavy quarks is predicted to be smaller than for the light quarks due to a suppression of the phase space for gluon radiation for large masses of the quarks (the so called “dead cone” effect [ 3]). Due to the interaction of heavy quarks with the medium, heavy flavor particle is expected to exhibit none zero elliptic flow v2 [ 4]. The strength of the heavy quark flow in combination with the degree of heavy quark suppression provide crucial information on the nature of the heavy quark interaction with the medium and are therefore very important for the understanding of the medium properties [ 5].
