Phys. Rev. Lett. 72, 2324–2327 (1994)Proposed new signal for scalar top-squark bound-state productionReceived 4 October 1993; published in the issue dated 11 April 1994 We study the production and decay of a scalar (t̃1t̃1*) bound state σt̃1 at hadron supercolliders, where t̃1 is the lighter scalar top eigenstate. If t̃1 has no tree-level 2-body decays, the dominant decay modes of σt̃1 are gg or, if mh<mt̃i≪mt̃2, a pair of light scalar Higgs bosons h. Nevertheless, the branching ratio into two photons is often large enough to yield a detectable signal. © 1994 The American Physical Society URL:
