The Essence of Decay — Redistribution of the Projection Coupling Factor x

Particle decay is traditionally understood as the transformation of one particle into other particles, governed by various conservation laws. Based on World Quantum Theory (WQT), this paper proposes that the essence of decay is not particle transformation, but the redistribution of the projection coupling factor x. The x value of a particle describes its "state address" on the current projection layer. When decay occurs, the initial particle's xinitial is split into the x values of the final-state particles x1,x2,…, while satisfying a weighted conservation of x (equivalent to the conservation of energy, momentum, and angular momentum). The electron is stable because x=2π is a local potential well bottom on Earth's projection layer, with no lower x to jump to. The muon is unstable because its xμ lies in 1<xμ<2π, allowing it to decay to x=2π (electron) and x>2π (neutrinos). This paper argues that decay is not "death," but the redistribution of x — a particle moves from one state address to another.
