In 2001, a supersymmetric model was proposed to relate the axion scale tothat of neutrino mass seesaw. Whereas this scenario is realistic, the particlesassociated with this mechanism are either too heavy or too weakly coupled forthem to be observed (other than the axion itself or perhaps the axino). Avariation of that model is here proposed which allows significant mixing of theHiggs boson with a new singlet related to the saxion (the scalar partner of thepseudoscalar axion), rendering it possible to be observed at the Large HadronCollider (LHC). With the addition of exotic color superfields, this alsobecomes a specific realization of how the production of such a Higgs hybrid maybe suppressed or enhanced at the LHC, which is very relevant to ongoingexperimental efforts to find the Higgs boson.
