Two-photon production of pseudoscalar glueballs.

Abstract

Using a previously calculated distribution amplitude, we calculate the normalized differential cross section for two-photon pseudoscalar glueball plus meson production, $\ensuremath{\gamma}+\ensuremath{\gamma}\ensuremath{\rightarrow}G+{\ensuremath{\pi}}^{0}$. We compare to a previous calculation and to $\ensuremath{\gamma}+\ensuremath{\gamma}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{0}+{\ensuremath{\pi}}^{0}$.
