Nuclear modification and elliptic flow measurements for ϕ mesons at image d+Au and Au+Au collisions by PHENIX Original Research Article

We report the first results of the nuclear modification factors and elliptic flow of the ϕ mesons measured by the PHENIX experiment at RHIC in high luminosity Au+Au collisions at View the MathML source. The nuclear modification factors RAA and RCP of the ϕ follow the same trend of suppression as π0ʹs in Au+Au collisions. In d+Au collisions at View the MathML source, the ϕ mesons are not suppressed. The elliptic flow of the ϕ mesons, measured in the minimum bias Au+Au events, is statistically consistent with other identified particles.
