Soft Photon theorem in the small negative cosmological constant limit

11 Feb 2021 Nabamita Banerjee Karan Fernandes Arpita Mitra

We study the effect of electromagnetic interactions on the classical soft theorems on an asymptotically AdS background in 4 spacetime dimensions, in the limit of a small cosmological constant or equivalently a large AdS radius $l$. This identifies $1/l^2$ perturbative corrections to the known asymptotically flat spacetime leading and subleading soft factors... (read more)
