The PHENIX detector at RHIC measured high p T identified hadron ratios in √ s N N = 200 GeV Au+Au collisions. Within the current systematic and statistical errors, p/p ratios that are measured up to 3.8 GeV/c are almost independent of both p T and centrality. The baryon to meson ratio is measured through p/π and p/π ratios up to 3.8 GeV/c, showing they are strongly centrality dependent.

Inclusive transverse momentum spectra of single electrons from Au+Au collisions have been measured at √ s N N = 130 GeV and 200 GeV at midrapidity by the PHENIX experiment at RHIC. After subtraction of background from photon conversions and light hadron decays, the spectra appear consistent with semileptonic decays of charmed particles.

New results on φ-meson production and elliptic flow v 2 measurements from RHIC 2004 run (Run-IV) have been reviewed. In addition, the di-hadron correlation function between the trigged φ and Ω and the associated soft particles was simulated. Knowledge about these results are discussed.

Transverse momentum spectra of identified π + , π − , K + , K − , p and p were measured by the PHENIX experiment at mid-rapidity in Au-Au collisions at √ s N N = 130 GeV over a broad momentum range. Inverse slope parameters and p t were measured in minimum bias events and as a function of the number of participating nucleons. The mass and centrality dependence of the inverse slope parameters an...
