Higher-spins on Taub-NUT and higher-spin Taub-NUT

Year: 2025

Type: article

Abstract: A bstract We consider higher-spin extensions of self-dual Yang-Mills (HS-SDYM) and self-dual Gravity (HS-SDGR), which are also truncations of chiral higher-spin gravity. Higher-spin fields can consistently propagate on gravitational instantons and we construct solutions to the higher-spin equations on the Taub-NUT background. We show that these solutions remain exact solutions of HS-SDYM. For HS-SDGR the perturbation theory converges for any given spin to give a higher-spin generalization of Taub-NUT and we identify a commutative non-associative algebra that governs the structure of the perturbation theory.
