The C ( x , y ) C(x,y) Paradigm: A Unified Spectral Theory of Spacetime and Matter from the Non-local Correlation Operator

This work presents the C(x, y) Paradigm - a unified quantum theory based on a single fundamental entity: a non-local correlation operator C^ defined on the product manifold M×M. Using the Spectral Action Principle from Non-Commutative Geometry, we rigorously demonstrate that both General Relativity and the Standard Model emerge as low-energy asymptotic limits of C^'s spectral expansion. The theory achieves ultraviolet finiteness through an intrinsic Gaussian form-factor e−σ2p2 that suppresses all high-energy divergences. Crucially, all fundamental constants - including the gravitational constant GG, gauge couplings, and Higgs mass (mH≈125.5) - are derived from the single scale Λ=1/σ and the algebraic structure AF=C⊕H⊕M3(C). The paradigm provides geometric explanations for three fermion generations via the Atiyah-Singer index theorem and resolves the cosmological constant problem through a two-stage Dynamic Spectral Screening mechanism. We propose three falsifiable experimental tests: detection of running tensor index in primordial gravitational waves, deviations in Casimir force measurements, and precision verification of the predicted strong coupling constant αs(MZ)≈0.1168.
