Measurements of charm and charmonium production by PHENIX

The PHENIX Experiment at RHIC has measured charmonium production using dileptons and open heavy flavor production via semileptonic decays in p + p, d + Au, and Au + Au collisions at root S-NN = 200 GeV. A nuclear dependence affecting J/psi production in d + Au collisions is observed. For electrons from heavy flavor decay in Au + Au collisions, the transverse momentum spectrum is observed to be strongly modified compared to scaled results from p + p collisions. An initial measurement of the azimuthal anisotropy parameter, v(2), for such electrons is reported.
