Self-dual theories, due to their nice properties, are good subjects to study celestial holography. In this paper, we developed a new formula to calculate the celestial color-ordered self-dual Yang-Mills amplitudes based on celestial Berends-Giele currents, which makes the leading OPE limit manifest. In addition, we explore some higher-order terms of OPE in the celestial self-dual Yang-Mills theory.trueGauge Symmetry | Global Symmetries | Scattering AmplitudesArticlehttps://link.springer.com/content/pdf/10.1007/JHEP03(2024)100.pdf10298479March 20246100arJournal6
