TECHNICAL EXTENSION OF COHERENT ORIENTATION SECTOR THEORY: Effective Field Theory, Higgs Portals, Renormalization, and Experimental Tests (OCDST Paper 2.2)

Orientation-Coupled Dark Sector Theory (OCDST) Paper 1/2 introduced an effectiveorientation-field framework capable of reorganizing relic dark matter while preserving Ein-steinian gravity for baryonic matter. Paper 2/2 proposed that the effective orientationfield may emerge from a deeper vacuum coherence geometry. Paper 2.1 established theperturbative survival conditions of the coherence-sector interpretation by deriving mathe-matical stability gates, cosmological dormancy conditions, gravitational-wave consistencyrequirements, and finite-response constraints from galaxy clusters.The present work extends the coherence-sector framework into a systematic EffectiveField Theory (EFT) description. Rather than introducing additional phenomenologicalassumptions, we construct the lowest-order gauge-invariant operators coupling the StandardModel to the coherence sector, investigate the resulting Higgs portal, examine perturbativequantum corrections, and identify the corresponding experimental signatures expected incollider physics.The analysis shows that the proposed coherence-sector interaction can be formulatedwithin a gauge-invariant effective field theory. Within representative weak-coupling parameterranges explored in this work, the framework remains compatible with current experimentalconstraints. We discuss one-loop corrections, renormalization-scale dependence, Higgs cou-pling modifications, and future precision tests at high-luminosity collider facilities. Togetherwith Paper 2.1, the present work extends the mathematical survival program into an EffectiveField Theory framework by providing a quantitative bridge between the coherence-sectorinterpretation and experimentally accessible observables
