Study on Coupling‑Evolution Mechanism of Matter‑Antimatter and Generation Law of Particle Steady‑State

To reveal the underlying mechanisms of fundamental physical phenomena including micro‑particle evolution, matter‑antimatter asymmetry and fixed particle chirality, this paper constructs a novel fractional‑charge three‑body coupling‑evolution model based on the original time‑superposition‑state theory of matter and antimatter. This paper proposes that ordinary matter possesses a quantum superposition state of “present‑future”, whereas antimatter takes a quantum superposition state of “present‑past”. Such time‑dimensional properties determine the unidirectionality and asymmetry of micro‑particle reactions. Different from the macroscopic celestial mechanics which is merely constrained by gravitation and kinetic energy, the evolution of micro‑quantum systems is jointly governed by four mechanisms: universal gravitation, Coulomb electromagnetic interaction, particle spin dynamics and time‑superposition state. Through systematic deduction of multiple three‑body coupling systems with varied fractional‑charge ratios, this paper fully distinguishes the photon annihilation channel, transient‑decay particle channel and exclusive proton steady‑state generation channel. Furthermore, mechanisms for neutrino dimensional drop, quantum superposition collapse upon observation and particle chirality fixation are established. The research results theoretically explain long‑standing puzzles in physics: the origin of proton’s unique steady‑state, the instability of cosmic antiprotons, fixed neutrino chirality and the uniqueness of quantum observation. This model provides brand‑new theoretical support for researches on micro‑particle structure, quantum‑collapse mechanism and unified‑field theory.
