摘要
本文基于Bilson-Thompson提出的组合先子拓扑模型(compositepreonstopologicalmodel,TM),提出了先子呈现空间假说(preonsemergingspacehypothesis,PESH),即携带同样电荷(0电荷或±e/3电荷)的3条先子(pre-ons)从粒子中向外延伸,构建出与其他粒子共享的各向同性三维空间。由PESH得到的4项规则经检验与标准模型的所有三代粒子相符合。应用PESH可以从几何/拓扑角度解释量子霍耳效应中的分数电荷准粒子、夸克禁闭及渐近自由、三维空间、粒子质量、宇称守恒及破缺、将引力子纳入TM、量子统计及自旋等物理现象。而且,基于PESH可以预言在特殊环境下存在带分数电荷粒子。本文并提出了两项实验以验证这些预言。
As an extension of Bilson-Thompson's Topological Model (TM), the Preons Emerging Space Hypothesis (PESH) is based upon a principal assumption: Three stretched out preons construct the 3-dimensional space. Three preons with the same electrical charge (0 or± e/ 3) in a particle stretched out construct the isotropic 3- dimensional space shared with other particles. Four rules derived from the PESH are checked in agreement with all three generations particles in the standard mod- el. From the geometry/topology viewpoint, PESH rules are used to interpret observed physical phenomena including: quasi-particles with fractional charges observed in quantum Hall effect experiments, quark confinement and asymptotic freedom, vacuum state and virtual particles, the reason for space having three dimensions, mass of particles, parity conservation and violation, in- troduction of graviton to the TM, quantum statistics and spin. PESH predicts the existence of fractional charged particles under special circumstances. Two confirmative experiments are proposed to verify the prediction as well as the PESH and TM.
