Heavy-flavor measurements with the PHENIX experiment at RHIC

摘要

The PHENIX experiment has measured the contribution of heavy-flavor decays to single-electron spectra in Au + Au collisions at roots(NN) = 130 GeV and 200 GeV at RHIC, providing a first measure of the total charm yield and its dependence on collision centrality at these energies. In addition, J/psi charmonium states were reconstructed by PHENIX in their dilepton decay channels in p+p and Au+Au collisions at roots(NN) = 200 GeV.
