Abstract (data abstract)

Measurement of the centrality dependance of the open charm production, from single electrons measurement, at the PHENIX experience, in Au+Au collisons at center-of-mass energy of200 GeV. The transverse momentum spectra (0.4<PT<4.0 GeV/c) of single electrons are presented, as a function of centrality The measurements are made at mid-rapidity (-0.35<y<0.35). The contribution to the raw specra from photon conversions and Dalitz decays are measured with a thin converter, which multiplies the photonic contribution by acertain factor. The photonic contribution can therefore be estimated and statistically removed.After that, the great majority of electrons forming the invariant mass spectra are supposed to come from heavy flavor decays The bottom production, even if included in the calculations, is considered to have almost no influence on the data, in the range of PT observed in this paper. The minimum bias trigger used in this study corresponds to (92.2 +2.5,-3.0)% of the 6.8 +- 0.5 barn Au+Au inelastic cross section.
