| Study of Charm and Beauty using electron-$D^0$ azimuthal correlations in the STAR experiment at RHIC |

| Content: |
The energy loss of heavy quarks in the hot and dense matter created in
high-energy nuclear collisions at RHIC, can be used to probe the
properties of the medium. Both charm and beauty quarks contribute to the non-
photonic electrons through their semi-leptonic decays. It is essential to
determine experimentally the relative contribution of charm and beauty quarks to
understand the observed suppression of non-photonic electrons at high pT
in central Au+Au collisions. The azimuthal angular correlations of non-
photonic electrons with the reconstructed $D\^{0}$ allow to disentangle the
contribution of charm and beauty to the electron spectrum.
We discuss the STAR measurement of non-photonic electron-$D^{0}$
azimuthal correlations in p+p collisions at 200 GeV. Furthermore, we show
preliminary results from the application of microvertexing techniques for charm
and beauty searches in Au+Au collisions at 200 GeV using the information of the
Silicon vertex tracker of STAR. |
