Abstract
We explore the possibility of measuring B-hadrons produced in heavy ion reactions at relativistic heavy ion collider through the semi-leptonic decay B → e + X with the STAR Heavy Flavor Tracker. We present a method to separately measure the production of charm and beauty hadrons by exploring the different impact parameter distributions of their decay electrons. The uncertainties of the transverse momentum distributions, nuclear modification factors and elliptic flow parameters of the electrons from heavy flavor decay are estimated. Relevant physics topics are discussed.
