Charm study via electron-hadron azimuthal correlations in p+p and d+Au $\sqrt{s_{NN}}=200$ GeV collisions
POSTER
Abstract
PHENIX data on single electron production indicate an excess of electrons over known light hadronic sources that has been attributed to open charm and beauty decays. The non-photonic electron yields are consistent with two different scenarios. One is the creation of a medium completely transparent to heavy quarks. The other is the creation of a highly opaque medium with the heavy quarks rescattering and hadronizing in the system. We can distinguish between these different scenarios by studying the electron-charged hadron azimuthal correlations with respect to the system size. The correlations in p+p and d+Au collisions provide a direct observation of the heavy quark jets and the baseline for possible shape modifications in the Au+Au central collisions. The method for extracting the non-photonic azimuthal correlations and the current results for p+p, d+Au at $\sqrt{s_{NN}}=200$ GeV PHENIX data will be presented.
