Description
We proposes a novel link between the hierarchy problem and Weakly Interacting Massive Particles (WIMPs), suggesting that the small mass of the Higgs boson arises from the universe’s WIMP-induced proximity to the critical boundary of a phase transition. Intriguingly, such a requirement aligns with the so-called “WIMP miracle”: a WIMP with mass around the weak scale and Standard Model couplings not only happens to have the correct thermal relic abundance to be the observed dark matter, it can also naturally destabilise the Higgs potential just above the weak scale. This coincidence may signify a more direct link between WIMP dark matter and Higgs naturalness than anticipated from traditional symmetry-based explanations. Using a Higgsino-like singlet–doublet model, we show that our Higgs criticality scenario is compatible with TeV-scale WIMP dark matter. It can be thoroughly probed in direct detection experiments, astrophysical signals and future collider searches. These findings further motivate a comprehensive exploration of the remaining heavy WIMP parameter space.
