The latest PHENIX results for particle production are presented in this paper. A suppression of the yield of high p_t (transverse momentum) hadrons in central Au+Au collisions is found. In contrast, direct photons are not suppressed in central Au+Au collisions and no suppression of high p_t particles can be seen in d+Au collisions. This leads to the conclusion that the dense medium formed in central Au+Au collisions is responsible for the suppression. It is as well found, that the properties of this medium are similar to the one of a liquid. Further measurements provide information about the chiral dynamics of the system.

The production of the low-mass dielectrons is considered to be a powerful tool to study the properties of the hot and dense matter created in the ultra-relativistic heavy-ion collisions. We present the preliminary results on the first measurements of the low-mass dielectron continuum in Au+Au collisions and the phi meson production measured in Au+Au and d+Au collisions at sqrt{s_NN} = 200 GeV performed by the PHENIX experiment.

Recent results on identified hadrons from the PHENIX experiment in Au+Au collisions at mid-rapidity at $sqrt{s_{NN}}$ = 200 GeV are presented. The centrality dependence of transverse momentum distributions and particle ratios for identified charged h adrons are studied. The transverse flow velocity and freeze-out temperature are extracted from $p_{T}$ spectra within the framework of a hydrodynamic collective flow model. Two-particle HBT correlations for charged pions are measured in different centrality selections for a broad range of transverse momentum of the pair. Results on elliptic flow measurements with respect to the reaction plane for identified particles are also presented.

The J/psi is considered to be among the most important probes for the deconfined quark gluon plasma (QGP) created by relativistic heavy ion collisions. While the J/psi is thought to dissociate in the QGP by Debye color screening, there are competing effects from cold nuclear matter (CNM), feed-downs from excited charmonia (chi_c and psi) and bottom quarks, and regeneration from uncorrelated charm quarks. Measurements that can provide information to disentangle these effects are presented in this paper.

The first results from Au-Au collisions at $sqrt{s_{NN}}$=130 GeV obtained with the PHENIX detector in the Year 2000 run at RHIC are presented. The mid-rapidity charged particle multiplicity and transverse energy per participating nucleon rise steadi ly with the number of participants, such that transverse energy per charged particle remains relatively constant as a function of centrality. Identified charged hadron spectra as well as $bar{p}/p$ and $K^+/K^-$ ratios are discussed. Charged particle and neutral pion transverse momentum distributions in peripheral nuclear collisions are consistent with point-like scaling. The spectra at high $p_t$ from central collisions are significantly suppressed when compared to a simple superposition of binary nucleon-nucleon collisions.
