Abstract

We investigate the spectrum of physical states in the W₃ string theory, up to level 2 for a multi-scalar string, and up to level 4 for the two-scalar string. The (open) W₃ string has a photon as its only massless state. By using screening charges to study the null physical states in the two-scalar W₃ string, we are able to learn about the gauge symmetries of the states in the multi-scalar W₃ string.
