Systematics of Identified Hadron Spectra at PHENIX

Mid-rapidity transverse momentum distributions for $π^\pm$, $K^\pm$, p and $\pbar$ are measured by the PHENIX experiment at RHIC in Au+Au, d+Au and p+p collisions at \ssnn=200GeV up to ~2--4GeV. Also particle ratios of $π^{-}/π^{+}$, $K^{-}/K^{+}$, $\pbar/p$, $p/π$ and $\pbar/π$ are measured, as well as the nuclear modification factor, all as a function of \pt and in every of the above collision systems. Finally, the measured p+p and Au+Au spectra are compared to the Buda-Lund hydro model.
