Evidence for two new0++mesons and a possible scalar decuplet

We present evidence for the existence of two new $I=0$ scalar mesons [${g}_{s}(1240)$ and ${S}^{*\ensuremath{'}}(1730)$] from an amplitude analysis of the reaction ${\ensuremath{\pi}}^{\ensuremath{-}}p\ensuremath{\rightarrow}{K}_{S}^{0}{K}_{S}^{0}n$ 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 ${J}^{\mathrm{PC}}={0}^{++}$ nonet. These results are in qualitative agreement with recent theoretical predictions of glucon-glucon bound states.
