Abstract

We discuss the physical spectrum for $W$ strings based on the algebras $B_{n}$ , $D_{n}$ , $E_{6}$ , $E_{7}$ and $E_{8}$ . For a simply-laced $W$ string, we find a connection with the $(h, h + 1)$ unitary Virasoro minimal model, where $h$ is the dual Coxeter number of the underlying Lie algebra. For the $W$ string based on $B_{n}$ , we find a connection with the $(2 h, 2 h + 2)$ unitary $N = 1$ super-Virasoro minimal model.
