# Asymptotic Symmetries in $(d+2)$-Dimensional Gauge Theories

## TL;DR

This paper demonstrates how soft photon and gluon theorems in higher-dimensional gauge theories correspond to Ward identities of asymptotic symmetries, extending the understanding of gauge symmetries at null infinity.

## Contribution

It generalizes the connection between soft theorems and asymptotic symmetries to higher dimensions and non-abelian gauge theories, revealing new symmetry structures.

## Key findings

- Soft photon theorem leads to Ward identities for large gauge transformations.
- Soft gluon theorems imply asymptotic symmetries in non-abelian theories.
- Extension of asymptotic symmetry analysis to $(d+2)$-dimensional spacetimes.

## Abstract

We show that the subleading soft photon theorem in a $(d+2)$-dimensional massless abelian gauge theory gives rise to a Ward identity corresponding to divergent large gauge transformations acting on the celestial sphere at null infinity. We further generalize our analysis to $(d+2)$-dimensional non-abelian gauge theories and show that the leading and subleading soft gluon theorem give rise to Ward identities corresponding to asymptotic symmetries of the theory.
