Topological Fields in Higher Spin Theory
arXiv:2603.08334 · doi:10.1016/j.physletb.2026.140480
Abstract
The equations for topological fields in the higher spin theory are considered. It is shown that these fields contain a finite number of degrees of freedom that justifies their naming. The issue of construction of gauge invariant functionals is addressed, and a gauge-invariant cubic action is constructed for the interacting physical and topological higher spin fields.
