Oscillating scalar potential and its implications for cosmic neutrino background searches
Abstract We propose a novel mechanism in which the mass-squared term of a scalar potential periodically switches sign due to an external oscillatory wave. As a result of this “potential oscillation,” the vacuum transitions between symmetry-broken and symmetry-restored phases. This repeated toggling...

| Summary: | Abstract We propose a novel mechanism in which the mass-squared term of a scalar potential periodically switches sign due to an external oscillatory wave. As a result of this “potential oscillation,” the vacuum transitions between symmetry-broken and symmetry-restored phases. This repeated toggling leads to a time-varying vacuum state that, through the scalar field’s couplings to other sectors, gives rise to interesting phenomenological consequences. As a concrete illustration, we demonstrate how these oscillations can open a new avenue for probing the cosmic neutrino background. |
