Abstract
We construct a simple and natural supersymmetric model where the dominant Higgs decay is followed by . In this case is compatible with all experimental searches, completely eliminating the fine-tuning otherwise required to satisfy Higgs search limits. The model extends the minimal supersymmetric standard model with singlet Higgs fields as well as vectorlike colored particles that mediate the decay . The is a pseudo-Nambu-Goldstone boson of a new global symmetry, and can naturally have any mass from a few GeV to . All interactions can be perturbative up to the GUT scale, and gauge coupling unification is preserved if the colored mediators come in complete GUT representations. In this case has a branching ratio, so may be observable. The colored particles that mediate the decay must be below the TeV scale, and can therefore be produced at the LHC. If these particles are stable on collider time scales, they will appear as -hadrons, a signal visible in early LHC running. A smoking-gun signal that the stable colored particles are mediators of is -hadron production in association with an . We show that this signal with is observable at the LHC with as little as of integrated luminosity. Observation of -hadrons plus missing energy would show that the superpartner of the -hadron is -parity odd, and therefore not an ordinary quark or gluon.
