时空对称性与Z_3分次夸克代数

Spacetime Symmetries and Z_3-graded Quark Algebra

Richard Kerner

摘要:

研究了一类具有立方$Z_3$ -不变本构关系的$Z_3$ -分次结合代数.在低维情况下,给出了这类代数的两个或三个生成元的不变形式。我们证明了在没有闵可夫斯基度量概念的情况下,由$SL(2, {\bf C})$群表示的Lorentz对称性是如何自然出现的,正如$Z_3$ -分次三次代数的不变性群及其本构关系一样.它的表示是根据泡利矩阵。这种结构与定义夸克态的运营商的关系也被认为是,并介绍了克莱因-戈登方程的三阶模拟。其解的立方积可以为满足狄拉克方程和克莱因-戈登方程的常见波函数提供基础。

英文摘要:

We investigate certain $Z_3$-graded associative algebras with cubic $Z_3$-invariant constitutive relations. The invariant forms on finite algebras of this type are given in the low dimensional cases with two or three generators. We show how the Lorentz symmetry represented by the $SL(2, {\bf C})$ group emerges naturally without any notion of Minkowskian metric, just as the invariance group of the $Z_3$-graded cubic algebra and its constitutive relations. Its representation is found in terms of Pauli matrices. The relationship of this construction with the operators defining quark states is also considered, and a third-order analogue of the Klein-Gordon equation is introduced. Cubic products of its solutions may provide the basis for the familiar wave functions satisfying Dirac and Klein-Gordon equations.
