SIM(1)超空间中的Chern-Simons理论

Chern-Simons Theory in SIM(1) Superspace

Jiří Vohánka, Mir Faizal

摘要:

本文用SIM(1)超空间形式分析了三维超对称Chern-Simons理论。洛伦兹对称性破缺到SIM(1)对称性,打破了洛伦兹不变量理论的一半超对称性。因此,当洛伦兹对称性被破缺为SIM(1)对称性时,具有N=1超对称性的洛伦兹不变量Chern-Simons理论的超对称性将被破缺为N=1/2超对称性。首先,我们将使用N=1个超场的SIM(1)投影来写陈-西蒙斯作用量。然而,由于这些投影的SIM(1)变换非常复杂,我们将定义SIM(1)超场,它们在SIM(1)变换下简单地变换。然后我们将用这些SIM(1)超场表示陈-西蒙斯作用量。此外,我们将分析这个陈-西蒙斯理论的规范对称性。这是第一次在没有边界的流形上构造N=1/2超对称的Chern-Simons理论。

英文摘要:

In this paper, we will analyse a three dimensional supersymmetric Chern-Simons theory in SIM(1) superspace formalism. The breaking of the Lorentz symmetry down to the SIM(1) symmetry, breaks half the supersymmetry of the Lorentz invariant theory. So, the supersymmetry of the Lorentz invariant Chern-Simons theory with N=1 supersymmetry will break down to N=1/2 supersymmetry, when the Lorentz symmetry is broken down to the SIM(1) symmetry. First, we will write the Chern-Simons action using SIM(1) projections of N=1 superfields. However, as the SIM(1) transformations of these projections are very complicated, we will define SIM(1) superfields which transform simply under SIM(1) transformations. We will then express the Chern-Simons action using these SIM(1) superfields. Furthermore, we will analyse the gauge symmetry of this Chern-Simons theory. This is the first time that a Chern-Simons theory with N=1/2 supersymmetry will be constructed on a manifold without a boundary.
