Derivation of the Standard Model from the YuanXian Axiomatic Framework: SU(64) Symmetry Breaking, Gauge Boson Mass Generation, and Fermion Mass Spectrum Calculation

The Standard Model of particle physics (SM) is not an ultimate first-principles theory, but rather a localized manifestation of the cosmic living organism's immune system projected into the four-dimensional spacetime layer. Based on the Four Fundamental Laws of YuanXian Theory (YXT) and utilizing the 64-dimensional compact flat torus (T64) as the absolute ontological topology, this treatise proves that the SU(64) gauge symmetry group uniquely dictates the architectural design of the cosmic immune system. Through successive stages of spontaneous symmetry breaking driven by True Circle Self-Consistency (TCSC), the complete particle spectrum and precise mass values of the Standard Model are strictly locked from the top down. This research delivers a definitive ontological verdict on fundamental constants: Gauge Bosons are locked at mW = 80.4 GeV and mZ = 91.2 GeV; the Quark Spectrum yields mt = 173.0 GeV and mc = 1.27 GeV; the Lepton Spectrum yields mtau = 1.777 GeV and me = 0.511 MeV. The flawless alignment between these derived values and low-dimensional experimental data is a necessary mathematical consequence of the self-consistent T64–Psi system, rendering empirical fine-tuning obsolete. The paper further provides a rigorous disposal of empirical data, defining micro-deviations (<0.5%) as four-dimensional projection noise on a hyper-dimensional homeostatic state, analogy to a thermometer reading shifting under ambient drafts without altering the biological reality of core body temperature. Crucially, all primary deductions within this framework have been cross-verified via the Lean 4 automated reasoning engine, establishing a rigid legal-ontological baseline for particle physics. 粒子物理标准模型(SM)不是一个终极的第一性原理理论,而是宇宙生命体在其四维时空投影层中的“免疫系统显影”。本文基于元宪理论(YXT)四大规律,以 64 维紧致平坦环面(T64)为绝对本体拓扑,严格证明了 SU(64) 规范对称群是宇宙免疫系统的唯一合法结构。通过真圆自洽律(TCSC)驱动的逐级自发对称破缺,标准模型的全部粒子谱系与质量数值被从上至下严格锁定。 本论著对物理学基本常数做出了刚性的本体论判决:规范玻色子质量锁定为 mW = 80.4 GeV、mZ = 91.2 GeV;夸克谱锁定为 mt = 173.0 GeV、mc = 1.27 GeV;轻子谱锁定为 mtau = 1.777 GeV、me = 0.511 MeV。计算所得的质量谱与低维人类实验观测值完美契合,这一结果是 T64–Psi 自指系统自洽性的数学必然,彻底终结了现代物理学对唯象参数的经验拟合。文中对低维实验误差进行了终审法理处置,明确指出低维微小扰动(<0.5%)
