Systematic measurements of light vector mesons at RHIC-PHENIX

Forskningsoutput: TidskriftsbidragArtikel i vetenskaplig tidskrift

Abstract

The PHENIX experiment at RHIC has measured and ω meson production in p+p, d+Au and Au+Au collisions for GeV at mid-rapidity. Systematic measurements of light vector mesons for several decay channels provide information about properties of the strongly interacting matter produced in relativistic heavy-ion collisions. We present transverse momentum spectra and nuclear modification factors for and ω mesons. Transverse momentum spectra are compared among different decay channels to discuss yield modification which results from mass modification in the hot medium. We compare the nuclear modification factors of various mesons and discuss differences of their suppression patterns.
