Open charm measurement with HFT at STAR
Abstract
Thermalization is one of the key questions in understanding the matter created in Au+Au collisions at RHIC. Heavy-flavor quark collectivity could be used to indicate the degree of thermalization of the light-flavor quarks. Heavy quark energy loss could give important information on color charge density of the medium. Direct reconstruction of open charm hadrons is essential for these measurements. The Heavy Flavor Tracker (HFT) is a proposed upgrade of the STAR experiment. Full GEANT simulation of tracking with HFT was performed, showing its excellent capability to reconstruct open charm hadrons in broad p T range at midrapidity. Estimated errors on measurement of D 0 meson υ 2 and R CP are presented.
