超对称和环量子引力理论与粒子物理中的统一

Supersymmetry,Loop Quantum Gravity and Unifications in Particle Physics

在超对称理论中引入与自旋无关的超旋、超同位旋和各种超对称变换,从而统一描述玻色子和费米子.同时讨论了超对称和超弦中的各种相互作用及其它方面的统一,导出了环量子引力理论的4个定量结论,提出了可能存在从超弦到宇宙弦等不同尺度的泛弦.

First, some theories of supersymmetry and quantum gravity in particle physics are stated briefly. This paper introduces a super-spin, which is independent of spin, and super-isospin and various supersymmetric transformations, so that describes unification between bosons and fermions. Further, various unifications of different interactions and other aspects in supersymmetry and superstring are discussed. The four quantitative conclusions on the loop quantum gravity are derived. Finally, a possible existence of the extensive spring for different scales from superstring to cosmic string is proposed.
