矩阵模型中的规范对称性破缺

Gauge Symmetry Breaking in Matrix Models

Harald Grosse, Fedele Lizzi, Harold Steinacker

摘要:

我们认为,标准模型的某些特征,特别是费米子分配和对称性破缺,可以在描述非对易规范理论和引力的矩阵模型中得到体现。该机制是基于一些额外的(矩阵)维度的存在。这些额外的维度与通常的Gronewold-Moyal型非对易几何不同,虽然作用非常不同,但让人想起Connes-Lott模型。

英文摘要:

We argue that some features of the standard model, in particular the fermion assignment and symmetry breaking, can be obtained in matrix model which describes noncommutative gauge theory as well as gravity in an emergent way. The mechanism is based on the presence of some extra (matrix) dimensions. These extra dimensions are different from the usual ones which give to a noncommutative geometry of the Gronewold-Moyal type, and are reminiscent of the Connes-Lott model, although the action is very different.
