Abstract
Data taken over the last several years have demonstrated that RHIC has created a hot, dense medium with partonic degrees of freedom. Identified particle spectra at high transverse momentum () and heavy flavor are thought to be well calibrated probes thus serve as ideal tools to study the properties of the medium. We present distributions of particle ratios in p+p collisions from STAR experiment to understand the particle production mechanisms. These measurements will also constrain fragmentation functions in hadron-hardon collisions. In heavy ion collsions, we highlight: 1) recent measurements of strange hadrons and heavy flavor decay electrons up to high to study jet interaction with the medium and explore partonic energy loss mechanisms; and 2) and high measurements to study the effect of color screening and other possible production mechanisms.
