> Title:
> Heavy Quark Production in p + p and Energy Loss and
> Flow of Heavy Quarks in Au+Au Collisions at √s_NN = 200 GeV
>
> Abstract:
> Transverse momentum (p^e_T) spectra of electrons from
> semileptonic weak decays of heavy flavor mesons in the range
> of 0.3 < p^e_T < 9.0 GeV/c have been measured at mid-rapidity
> (|η| < 0.35) by the PHENIX experiment at the Relativistic Heavy Ion
> Collider in p+p and Au+Au collisions at √s_NN = 200 GeV. The nuclear
> modification factor R_AA with respect to p+p collisions indicates sub-
> stantial energy loss of heavy quarks in the produced medium. In
> addition, the azimuthal anisotropy parameter v2 has been measured
> for 0.3 < p^e_T < 5.0 GeV/c in Au+Au collisions. Comparisons of RAA
> and v2 are made to various model calculations.
