Asymptotic analysis of sub-leading soft photon theorem in four dimension

Due to IR divergence logarithm terms appear in the sub-leading
soft theorem in four dimension. Recently Sahoo and Sen have obtained loop
corrected sub-leading soft photon and graviton theorems. Campiglia and
Laddha have proposed Ward identities of S-matrix for the loop corrected
soft photon theorem in the absence of gravity. We focus on constructing
asymptotic conserved charges related to sub-leading soft photon theorem in
the presence of gravity.
