Measurement of light mesons at RHIC by the PHENIX experiment

Abstract

The PHENIX experiment at RHIC has measured a variety of light neutral mesons (${\pi }^0$, K${}_S^0$, $\eta$, $\omega$, ${\eta }^{\prime }$, $\varphi$) via multi-particle decay channels over a wide range of transverse momentum. A review of the recent results on the production rates of light mesons in p+p and their nuclear modification factors in d+Au, Cu+Cu and Au+Au collisions at different energies is presented.
