Abstract
algebra is an infinite dimensional Lie algebra which is known to be the symmetry algebra of some gauge theories. It is a "coloured version" of the . In this paper we write down all possible invariant (celestial) OPEs between two positive helicity outgoing gluons and also find the Knizhnik-Zamolodchikov type null states for these theories. Our analysis hints at the existence of an infinite number of invariant gauge theories which include the (tree-level) MHV-sector and the self-dual Yang-Mills theory.
