Chemical equilibration of $\pi$, $\varrho$ and $\omega$ mesons in ultra-relativistic nuclear collisions
I estimate the degree of local chemical equilibration for $\pi$, $\rho$ and $\omega$ mesons in ultra--relativistic nuclear collisions. The $\pi$ and $\rho$ mesons remain near chemical equilibrium in all cases, while the $\omega$ meson density is typically 30--50\% higher than the equilibrium value f...
