Abstract
We investigate a quantum relaxation mechanism for the vacuum energy density arising from the spontaneous symmetry breaking (SSB) SO(1,4)→ SO(1,3), driven by a Higgs field Φ in a MacDowell–Mansouri pre-geometric gravity framework. The theory predicts a countably infinite set of vacua, corresponding to distinct topological sectors, for a periodic Higgs potential with intervening barriers. This structure gives rise to a series of dualities and see-saw relations connecting fundamental scales – the Planck mass and the Cosmological Constant – to topological parameters such as the Gauss–Bonnet coupling and the θ-term, all of which emerge only after SSB. A striking consequence is the quantization of the vacuum energy into discrete levels. Starting from a vacuum expectation value ⟨ Φ ⟩ = v1 associated with a large vacuum energy, the system evolves via quantum tunneling through the infinite landscape of minima. Crucially, we demonstrate that the transition probability is maximized for the ordered sequence Λ 1> ⋯> Λ k > ⋯, where the Cosmological Constant decreases monotonically toward the asymptotic attractor Λ ∞ = 0.

AB - We investigate a quantum relaxation mechanism for the vacuum energy density arising from the spontaneous symmetry breaking (SSB) SO(1,4)→ SO(1,3), driven by a Higgs field Φ in a MacDowell–Mansouri pre-geometric gravity framework. The theory predicts a countably infinite set of vacua, corresponding to distinct topological sectors, for a periodic Higgs potential with intervening barriers. This structure gives rise to a series of dualities and see-saw relations connecting fundamental scales – the Planck mass and the Cosmological Constant – to topological parameters such as the Gauss–Bonnet coupling and the θ-term, all of which emerge only after SSB. A striking consequence is the quantization of the vacuum energy into discrete levels. Starting from a vacuum expectation value ⟨ Φ ⟩ = v_1 associated with a large vacuum energy, the system evolves via quantum tunneling through the infinite landscape of minima. Crucially, we demonstrate that the transition probability is maximized for the ordered sequence Λ _1> ⋯> Λ _k > ⋯, where the Cosmological Constant decreases monotonically toward the asymptotic attractor Λ _∞ = 0.
