Bell Correlations from Scalar-Time Spectral Closure: Emergent SU(2) Measurement Geometry in Time–Scalar Field Theory

Bell correlations represent one of the deepest structural features of quantum mechanics. Experimental violations of Bell inequalities demonstrate that observed two-state correlations cannot be reproduced by classical local hidden-variable probability spaces satisfying Kolmogorov factorization constraints. Standard quantum mechanics accounts for these violations through Hilbert-space geometry, projector-valued measurements, and noncommuting observables. However, the geometric origin of this structure is normally postulated rather than derived. In this paper we investigate whether the measurement geometry underlying Bell correlations can emerge naturally from the spectral closure structure of Time–Scalar Field Theory (TSFT). The goal is not to replace quantum mechanics, nor to construct a classical hidden-variable model reproducing Bell violations. Instead, the objective is narrower and mathematically sharper: to determine the conditions under which admissible scalar-time closure sectors become equivalent to quantum two-state measurement geometry. Starting from the scalar-time field Θ(x^μ) and its associated fluctuation operator, we construct a self-adjoint spectral problem governing admissible coherence modes. Under finite-energy, normalizability, and phase-return conditions, the admissible spectrum becomes discrete. We then examine degenerate two-dimensional closure eigenspaces and show that closure-preserving basis transformations naturally induce unitary rotational structure. After quotienting by physically irrelevant global phase, the admissible state geometry reduces to an emergent SU(2)-covariant two-state manifold. Within this framework, binary measurements arise as closure-compatible projection operations on the degenerate sector. The associated correlation function acquires the form E(a, b) = −a · b, matching the standard quantum singlet-state correlation law. Maximization of the corresponding Clauser–Horne–Shimony–Holt (CHSH) functional then yields the Tsirelson bound S_max = 2√2, as a geometric consequence of closure-preserving scalar-time measurement structure. The derivation presented here does not assume Hilbert-space quantum mechanics as an initial axiom. Rather, the central claim is that under sufficiently constrained spectral closure conditions, the admissible geometry of scalar-time coherence sectors becomes mathematically equivalent to the two-state measurement geometry responsible for Bell correlations.
