An Effective Toy Model Inspired by the Gluon Mass Gap via β-Vacuum

We present a non-perturbative toy model with an infrared mass scale inspired by QCD, valid for Euclidean momenta Q ≤ m_gap. The β-Vacuum is defined by the Lagrangian Lβ = β/4 (∂μΦᵃ ∂ᵐΦᵃ)² + α/2 Φᵃ □² Φᵃ + m₀²/2 Φᵃ Φᵃ with a = 1,...,8. We prove strict monotonicity of the associate...
