超对称QCD与非对易几何

Supersymmetric QCD and noncommutative geometry

Thijs van den Broek, Walter D. van Suijlekom

摘要:

利用Chamseddine和Connes的谱作用原理,我们从非对易流形导出了超对称量子色动力学。在回顾了非对易几何中的Einstein-Yang-Mills系统之后,我们详细地证明了它具有超对称性。然后通过构造一个合适的非对易自旋流形(即谱三元组),将这个非对易模型推广到夸克、方子、胶子和胶子理论。粒子在谱三元组中处于它们的自然位置:夸克和胶子作为希尔伯特空间中的费米子,胶子和方子作为(广义)狄拉克算子的内部波动,通过流形上的矩阵值函数代数。谱作用量原理应用于这个谱三元组给出了超对称QCD的拉格朗日量,包括方子的软超对称破缺质量项。我们发现这些结果与物理文献中的结果是一致的。

英文摘要:

We derive supersymmetric quantum chromodynamics from a noncommutative manifold, using the spectral action principle of Chamseddine and Connes. After a review of the Einstein-Yang-Mills system in noncommutative geometry, we establish in full detail that it possesses supersymmetry. This noncommutative model is then extended to give a theory of quarks, squarks, gluons and gluinos by constructing a suitable noncommutative spin manifold (i.e. a spectral triple). The particles are found at their natural place in a spectral triple: the quarks and gluinos as fermions in the Hilbert space, the gluons and squarks as bosons as the inner fluctuations of a (generalized) Dirac operator by the algebra of matrix-valued functions on a manifold. The spectral action principle applied to this spectral triple gives the Lagrangian of supersymmetric QCD, including soft supersymmetry breaking mass terms for the squarks. We find that these results are in good agreement with the physics literature.
