ECOF Prediction: Multi-Lepton Angular Asymmetries in ttZ Production

Abstract The Energy-Consciousness Observer Framework (ECOF) predicts that multi-lepton final states, which involve multiple simultaneous observer-field couplings, should exhibit distinctive angular asymmetries arising from interference between mass-dependent coupling terms. This paper presents a testable prediction for ATLAS and CMS Run 3 ttZ production data in the four-lepton channel (ttZ → bℓνb̄ℓ̄νℓ⁺ℓ⁻): the angular distribution of muon pairs should show a measurable asymmetry in the opening angle distribution that is absent in electron pairs. Specifically, we predict a normalized asymmetry parameter A_θ (μμ) ≈ 0. 03 ± 0. 01, while A_θ (ee) should be consistent with zero. This prediction arises from ECOF's mass-dependent coupling (κ ∝ m_ℓ), which creates interference patterns in systems with multiple leptons that are absent in single-lepton channels. The Standard Model predicts symmetric angular distributions for both electron and muon pairs, making this a clean test of observer-field coupling in multi-particle final states. The experimental test requires reconstructing four-lepton events from Run 3 ttZ data and measuring opening-angle distributions separately for μμ and ee pairs.
