Description
We study the prospects for LHC discovery of a narrow resonance that decays
to two Higgs bosons, using the final state of two photons and two bottom
jets. Our work is motivated in part by a scenario in which two-body
flavor-preserving decays of the top squark are kinematically forbidden.
Stoponium, a hadronic bound state of the top squark and its anti-particle,
will then form, and may have a large branching fraction into the two Higgs
boson final state. We estimate the cross-section needed for a 5-sigma
discovery at the 14 TeV LHC for such a narrow di-Higgs resonance, using
the invariant mass distributions of the final state bottom jets and
photons, as a function of the integrated luminosity. The results are also
applicable to any other di-Higgs resonance produced by gluon fusion.
