    "abstract": "I estimate the degree of local chemical equilibration for $\\pi$, $\\rho$ and\n$\\omega$ mesons in ultra--relativistic nuclear collisions. The $\\pi$ and $\\rho$\nmesons remain near chemical equilibrium in all cases, while the $\\omega$ meson\ndensity is typically 30--50\\% higher than the equilibrium value for O+Ag\ncollisions at $\\sqrt{s}=20$ GeV. If chemical reactions are turned off, the\n$\\omega$ meson density is much larger, 2.5--3 times its equilibrium value.\nThus, $\\omega$ mesons may provide the most sensitive tests for the degree of\nchemical equilibration in nuclear collisions.",
