次次领先软引力子对称性与MHV引力子散射振幅

Subsubleading soft graviton symmetry and MHV graviton scattering amplitudes

Shamik Banerjee, Sudip Ghosh, Sai Satyam Samal

摘要:

在arXiv:2008.04330中指出,超平移和$\overline{SL(2,\mathbb C)}$电流代数对称性,对应于主导和次主导软引力子定理,足以确定树级MHV引力子散射振幅。在本文中,我们阐明了次次领导软引力子定理在这方面的作用。

英文摘要:

In arXiv:2008.04330 it was shown that supertranslation and $\overline{SL(2,\mathbb C)}$ current algebra symmetries, corresponding to leading and subleading soft graviton theorems, are enough to determine the tree level MHV graviton scattering amplitudes. In this note we clarify the role of subsubleading soft graviton theorem in this context.
