A Constructive Einstein–Cartan–Yang–Mills Theory with Positive Mass Gap in Four Dimensions

Abstract

We construct Euclidean Yang–Mills on ℝ4 for compact simple gauge groups (e.g., SU(N)) and prove OS0–OS4 at any fixed slab thickness t>0 via a regulator- and coupling-uniform Harris mixing of the slab boundary dynamics. Reflection positivity holds on the gauge-invariant subalgebra; transfer contraction implies a strictly positive Hamiltonian mass gap after OS reconstruction. Nonperturbative Slavnov–Taylor/BRST identities are established, with torsion in a BRST doublet and decoupled from gauge-invariant correlators. A lattice anchor corroborates slab-wise mixing and the gap. The framework is regulator-uniform, corridor-free, and independent of compactness assumptions.
