2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/44921We study the decays of a scalar \stst\ bound state \sigst, where \st\ is the lighter stop eigenstate. If \st\ has no tree--level 2--body decays, the dominant decay modes of \sigst\ are $gg$ or, if $m_h < \mst \ll \mstt$, a pair of light scalar Higgs bosons $h$. The best signal for \sigst\ production at hadron colliders is probably its decay into two photons.7 pages and 3 figures available from DREES@WISCPHEN, preprint nos. MAD/PH/782, KEK-TH-368.
