Description
The apparent fine-tunings of the Standard Model Higgs potential may be a consequence of its near-criticality. If its parameters are selected by an underlying mechanism that places the theory near criticality, then the scale of vacuum instability sets an upper bound on the Higgs mass. This reframes the hierarchy problem as a consequence of vacuum metastability and predicts new physics that destabilizes the Higgs potential at or just above the electroweak scale. Working within this hypothesis, I will present a new physics scenario that achieves a competitive metastability bound on the Higgs mass while simultaneously explaining the origin of neutrino masses and the production of dark matter. This scenario predicts sharp experimental targets correlated across the neutrino and dark sectors, with decisive experimental signatures in near-future collider searches that will conclusively test the broader class of models it represents.
