$\mathcal{N} =2$超空间中的Lorentz对称破缺

Lorentz Symmetry Breaking in $\mathcal{N} =2$ Superspace

Mir Faizal, Prince A. Ganai

摘要:

本文将研究具有$\mathcal{N} =2$超对称性的三维理论的形变。这个理论会因常向量场的存在而变形。这种变形将破坏洛伦兹对称性。因此,我们将使用$\mathcal{N} =2$以太超空间来分析这个理论。$\mathcal{N} =2$以太超空间将由通常的$\mathcal{N} =2$超空间的变形得到。这将通过使三维$\mathcal{N} =2$超对称的生成元变形来完成。在分析了这个变形超代数之后,我们将导出这个变形超空间中的超空间传播子的显式表达式。最后,我们将使用这些传播子进行微扰计算。

英文摘要:

In this paper, we will study the deformation of a three dimensional theory with $\mathcal{N} =2$ supersymmetry. This theory will be deformed by the presence of a constant vector field. This deformation will break the Lorentz symmetry. So, we will analyse this theory using $\mathcal{N} =2$ aether superspace. The $\mathcal{N} =2$ aether superspace will be obtained from a deformation of the usual $\mathcal{N} =2$ superspace. This will be done by deforming the generators of the three dimensional $\mathcal{N} =2$ supersymmetry. After analysing this deformed superalgebra, we will derive an explicit expression for the superspace propagators in this deformed superspace. Finally, we will use these propagators for performing perturbative calculations.
