The detection of an oscillating pattern in the bispectrum of densityperturbations could suggest the existence of a high-energy second minimum inthe Higgs potential. If the Higgs field resided in this new minimum duringinflation and was brought back to the electroweak vacuum by thermal correctionsduring reheating, the coupling of Standard Model particles to the inflatonwould leave its imprint on the bispectrum. We focus on the fermions, whosedispersion relation can be modified by the coupling to the inflaton, leading toan enhanced particle production during inflation even if their mass duringinflation is larger than the Hubble scale. This results in a large non-analyticcontribution to non-Gaussianities, with an amplitude $f_{\rm NL}$ as large as$100$ in the squeezed limit, potentially detectable in future 21-cm surveys.Measuring the contributions from two fermions would allow us to compute theratio of their masses, and to ascribe the origin of the signal to a new Higgsminimum. Such a discovery would be a tremendous step towards understanding thevacuum instability of the Higgs potential, and could have fascinatingimplications for anthropic considerations.
