Charm reconstruction using a micro-vertexing technique and STAR silicon vertex detectors

The energy loss measurements of heavy quarks are a unique probe of the hot and dense medium created in the heavy ion collisions at RHIC. Most of the heavy flavor measurements at RHIC are done through the semileptonic decay channel. Since both charm and bottom contribute to the non-photonic electron spectrum, the relative yield of charm and bottom are highly uncertain in such measurements. A direct measurement of charm can resolve this ambiguity
