The Settlement Origin of Matter-Antimatter Asymmetry: Two-Phase Information Conservation and the Selection of a Bias Parameter

Abstract The matter-antimatter asymmetry of the universe—why the observable universe is composed almost entirely of matter—is one of the most fundamental unsolved puzzles in particle physics and cosmology. Sakharov’s three conditions identify the necessary ingredients for generating an asymmetry, yet the Standard Model’s CP violation strength is at least eight orders of magnitude too small to account for the observed baryon-to-photon ratio. High-energy collider experiments further reveal a contrasting picture: at extreme energies, matter and antimatter are created and annihilated with perfect symmetry. This paper proposes a unified solution within the two-phase information conservation framework: matter-antimatter asymmetry results from the activation of a “bias parameter” ϵbias during the initialization of the information settlement network between the material phase (Ξ) and the information phase (Ω). The underlying “information duality grammar” of the Ξ-field ensures strict debit-credit balance in settlement—the symmetry revival observed in antihyperhelium-4 experiments is a transient flashback of this primitive grammar. During a non-equilibrium phase transition in the early universe, the bias parameter modifies the two-phase settlement channel, creating a matter excess of one part in ten billion, which accounts for all visible matter in the universe today. This framework reinterprets Sakharov’s three conditions as the execution mechanism of settlement bias rather than independent requirements, and predicts that Majorana neutrinos embody the “foldability” of the information duality grammar. We present three testable predictions: a gravitational wave signal from a strongly first-order electroweak phase transition, a positive result from neutrinoless double-beta decay experiments, and a cosmic-ray “echo” of primordial antimatter remnants. This work unifies matter-antimatter asymmetry with quantum measurement, black hole information processing, dark energy cosmology, quantum entanglement, the Higgs mechanism, the third law of thermodynamics, and the arrow of time under a single cross-scale information settlement paradigm.
