Recent heavy flavor measurements from the PHENIX experiment

We review results from three recent papers pertaining to heavy flavor interactions in heavy ion collisions. First, the yield and azimuthal anisotropy of electrons from heavy flavor decays in 62.4 GeV Au+Au collisions are presented. Contrary to suppression in 200 GeV collisions, the yield per binary collision is enhanced with respect to the yield from p+p collisions at the same energy. Secondly, we show a precise determination of the bottom cross section in d+Au collisions at 200 GeV/c   using the transverse momentum and mass-dependence of e+e−e+e− pairs from semileptonic heavy flavor decays. Lastly, we present the correlations of e±–μ∓e±–μ∓ pairs from charm decays between midrapidity electrons and forward rapidity muons in d+Au and p+p collisions at 200 GeV. We find that the pair yield at large azimuthal opening angle is suppressed in d+Au collisions with respect to p+p collisions.
