The properties of the phi-meson have been measured via its e+e- and K+K- decay channels in Au+Au collisions at sqrt{s_NN} = 200 GeV by the PHENIX experiment. The preliminary yields and temperatures derived for the minimum bias and several…
The PHENIX experiment at RHIC has measured $\omega$ and $\phi$ mesons in $p+p$, $d+Au$ and $Au+Au$ collisions at \sqn = 200 GeV via both hadronic and di-electron decay channels. The transverse momentum spectra as measured in different decay…
Light vector mesons are among the most informative probes to understand the strongly coupled Quark Gluon Plasma created at RHIC. The suppression of light mesons at high transverse momentum, compared to expectations from scaled $p+p$…
The PHENIX experiment at RHIC measured K0S, eta and omega-meson production at high pT in p+p, d+Au and Au+Au collisions at sqrt(s_NN)=200 GeV. Measurements performed in different hadronic decay channels give consistent results. This paper…
The PHENIX experiment at RHIC measured production of the \omega- and \phi- mesons in p+p, d+Au and Au+Au collisions at \sqrt{s_NN} = 63 and 200 GeV. Particle properties were studied using hadronic and di-electron decay channels. Transverse…
We present the preliminary results on $\phi$ meson production in the $\phi \to K^{+}K^{-}$ and $\phi \to e^{+}e^{-}$ decay channels measured at mid-rapidity in $\sqrt{s}$ = 200 GeV d + Au collisions at RHIC by the PHENIX experiment. The…
We present the results on the mid-rapidity phi meson production in the K^{+}K^{-} decay channel in Au + Au collisions at sqrt(s_NN) = 200 GeV measured by the PHENIX experiment at RHIC. The spectral shape of the phi resonance, studied at…
The PHENIX experiment at RHIC has measured a variety of light neutral mesons ($\pi^{0}$, K$_{S}^{0}$, $\eta$, $\omega$, $\eta^{\prime}$, $\phi$) via multi-particle decay channels over a wide range of transverse momentum. A review of the…
A simultaneous measurement of the $\phi$ meson via its $K^{+} K^{-} $ and $e^{+} e^{-}$ decay channels was performed in Au + Au collisions at $\sqrt{s_{NN}}$ = 200 GeV at mid-rapidity by the PHENIX experiment. The preliminary minimum bias…
The PHENIX experiment at RHIC has measured the \phi-meson production at mid-rapidity in p+p, d+Au, Cu+Cu and Au+Au collisions at \sqrt{s_{NN}}=200 GeV via the K^+K^- decay mode. The transverse momentum spectra of the \phi-meson and the…
We present the first results of meson production in the K^+K^- decay channel from Au+Au collisions at sqrt(s_NN) = 200 GeV as measured at mid-rapidity by the PHENIX detector at RHIC. Precision resonance centroid and width values are…
We report a measurement of $\phi$ meson production in central Pb+Au collisions at E$_{lab}$/A=158 GeV. For the first time in heavy-ion collisions, $\phi$ mesons were reconstructed in the same experiment both in the K$^+$K$^-$ and the…
The PHENIX experiment at RHIC measured $\omega$, $\eta$ and $K_{S}^{0}$-meson production at high $p_{T}$ in $p+p$, $d+Au$ and $Au+Au$ collisions at $\sqrt{s_{NN}}=200$ $GeV$. Measurements performed in different hadronic decay channels give…
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…
PHENIX has measured the dielectron continuum in sqrt(s_(NN))=200 GeV Au+Au and p+p collisions. In minimum bias Au+Au collisions the dielectron yield in the mass range between 150 and 750 MeV/c^2 is enhanced by a factor of 3.4 +/- 0.2(stat.)…
In sqrt(sNN) = 200 GeV Au+Au collisions PHENIX reported a significant enhancement in the low-mass region (0.1 < m_ee < 0.7 GeV) of the dielectron spectrum, which is still not fully understood. Several theoretical works and an indirect…
PHENIX has measured the e^+e^- pair continuum in sqrt(s_NN) = 200 GeV Au+Au and p+p collisions over a wide range of mass and transverse momenta. While the p+p data in the mass range below the phi meson are well described by known…
The first measurement of the dielectron continuum at RHIC energies was performed by the PHENIX experiment for Au+Au collisions at sqrt(s_{NN}) = 200 GeV. Mass spectra for different centralities are presented and compared with the…
PHENIX has measured $e^+e^-$ pairs from p+p and Au+Au collisions as function of mass and $p_T$. The data can be used to probe the properties of dense matter formed in Au+Au collision. The relation between electron pairs and virtual photons…
Measurements of light hadron production in ultrarelativistic nuclear collisions provide essential insight into final-state effects arising from both hot and cold nuclear matter. They probe collective behavior, hadronization via…
