Abstract

We present evidence for the existence of two new $I = 0$ scalar mesons [ $g_{s} (1240)$ and $S^{*'} (1730)$ ] from an amplitude analysis of the reaction $π^{-} p \to K_{S}^{0} K_{S}^{0} n$ at 23 GeV/c. An examination of the mass splittings present shows that neither of these states can be easily assigned to a (near) ideally mixed $J^{PC} = 0^{+ +}$ nonet. These results are in qualitative agreement with recent theoretical predictions of glucon-glucon bound states.
