Nuclear modification and elliptic flow measurements for phi mesons at root s(NN)=200 GeV d+Au and Au+Au collisions by PHENIX

摘要

We report the first results of the nuclear modification factors and elliptic flow of the phi mesons measured by the PHENIX experiment at RHIC in high luminosity Au+Au collisions at root(s(NN)) = 200 GeV. The nuclear modification factors R-AA and R-CP of the phi follow the same trend of suppression as pi(0)'s in Au+Au collisions. In d+Au collisions at root(s(NN)) = 200 GeV, the phi mesons are not suppressed. The elliptic flow of the phi mesons, measured in the minimum bias Au+Au events, is statistically consistent with other identified particles.
