  We elaborate on the hypothesis that in high energy hadron hadron and nucleus
nucleus collisions the lowest mass glueballs are copiously produced from the
gluon rich environment especially at high energy density. We discuss the
particular glueball decay modes: $0^{++}, 2^{++} \to K \bar{K}$ and $0^{++} \to
\pi^{+} \pi^{-} \ell^{+} \ell^{-}$.
