3d适形场,带有清单$sl(2,\mathbb{C})$

3d conformal fields with manifest $sl(2,\mathbb{C})$

Dmitry Ponomarev

摘要:

在本文中,我们构造了所有的短表示的$so(3,2)$与$sl(2,\mathbb{C})$对称性,由于使用$sl(2,\mathbb{C})$旋量。这种构造与先前提出的AdS ${}_4$中无质量场的旋量螺旋度形式有着天然的联系。然后,我们研究所得到的表示的么正性,确定它们作为最低重量的模块和共形场在三维Minkowski空间。最后,我们将这些结果与现有文献进行了比较,并讨论了这些表示在$so(3,2)$压缩到庞加莱代数下的性质。

英文摘要:

In the present paper we construct all short representation of $so(3,2)$ with the $sl(2,\mathbb{C})$ symmetry made manifest due to the use of $sl(2,\mathbb{C})$ spinors. This construction has a natural connection to the spinor-helicity formalism for massless fields in AdS${}_4$ suggested earlier. We then study unitarity of the resulting representations, identify them as the lowest-weight modules and as conformal fields in the three-dimensional Minkowski space. Finally, we compare these results with the existing literature and discuss the properties of these representations under contraction of $so(3,2)$ to the Poincare algebra.
