Burkhard U. W. Schwab, Anastasia Volovich
TL;DR
This paper proves a universal soft graviton theorem in arbitrary dimensions using the CHY scattering equations, applicable to both Yang-Mills theory and gravity at tree level.
Contribution
It provides a rigorous proof of the recently proposed soft graviton theorem in any dimension via the CHY formalism.
Findings
Universal soft graviton theorem validated in arbitrary dimensions
Applicable to both Yang-Mills and gravity theories
Proof at tree level using scattering equations
Abstract
We investigate the new soft graviton theorem recently proposed in arXiv:1404.4091. We use the CHY formula to prove this universal formula for both Yang-Mills theory and gravity scattering amplitudes at tree level in arbitrary dimension.
