Measurement of light mesons at RHIC by the PHENIX experiment

Abstract

The PHENIX experiment at RHIC has measured a variety of light neutral mesons ($π^{0}$, K$_{S}^{0}$, $η$, $ω$, $η^{\prime}$, $ϕ$) 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.
