Celestial $sw_{1+\infty}$ algebra in Einstein-Yang-Mills theory (2412.01647v2)
Published 2 Dec 2024 in hep-th and gr-qc
Abstract: From a study of the subleading structure of the asymptotic equations of motion in Einstein-Yang-Mills theory, we construct charges that are conserved up to quadratic order in non-radiative vacuum. We then show that these higher spin charges obey the celestial $sw_{1+\infty}$ symmetry algebra found earlier from the OPE of positive-helicity conformally soft gluons and gravitons.
