On Higher-spin Generalisations of String Theory
arXiv:hep-th/9304115 · doi:10.1142/S0217751X94000674
Abstract
We construct BRST operators for certain higher-spin extensions of the Virasoro algebra, in which there is a spin-$s$ gauge field on the world sheet, as well as the spin-2 gauge field corrresponding to the two-dimensional metric. We use these BRST operators to study the physical states of the associated string theories, and show how they are related to certain minimal models.
