2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/133203The PHENIX experiment at RHIC measured K0S, eta and omega-meson production at high pT in p+p, d+Au and Au+Au collisions at sqrt(s_NN)=200 GeV. Measurements performed in different hadronic decay channels give consistent results. This paper presents measured meson-to-pi0 ratios and Nuclear Modification factors in the most central d+Au and Au+Au collisions. No suppression seen in d+Au interactions is in contrast to a strong suppression of meson yields revealed in central Au+Au collisions at the same energy.4 pages 3 fig.
