PHENIX Studies of the Scaling Properties of Elliptic Flow at RHIC

Recent PHENIX elliptic flow ($v_2$) measurements for identified particles produced in Au+Au and Cu+Cu collisions at $\sqrt{s_{NN}}=200$ GeV are presented and compared to other RHIC measurements. They indicate universal scaling of $v_2$ compatible with partonic collectivity leading to the flow of light, strange and heavy quarks with a common expansion velocity field.Comment: Proceedings, Quark Matter 2006, Shanghai, Chin

A search for non-qqbar mesons in the WA102 experiment at the CERN Omega Spectrometer

A study of central meson production as a function of the difference in transverse momentum dPT of the exchanged particles shows that undisputed qqbar mesons are suppressed at small dPT whereas the glueball candidates are enhanced.Comment: 10 pages, Latex, 7 Figures, contribution to Hadron 9
