Goldstone和de Sitter超平移超光速粒子
Supertranslation Goldstone and de Sitter Tachyons
摘要:
超翻译Goldstone存在于$SL(2,\mathbb{C})$的某些“例外系列”表示中。有趣的是,三维de Sitter空间中的$m^2=-3$标量快子也处于相同的表示中。在本文中,我们分析了这些理论,侧重于表示理论方面,并强调,“模某些多项式”,有一个相应的对称群的酉表示。
英文摘要:
Supertranslation Goldstone lies in certain "exceptional series" representations of $SL(2,\mathbb{C})$. Interestingly, $m^2=-3$ scalar tachyon in three dimensional de Sitter space also lies in the same representation. In this note, we analyze these theories, focusing on representation-theoretical aspects, and emphasize that "modulo certain polynomials", there is a unitary representation of the corresponding symmetry group.
