Аннотация:
We study some low-lying physical states in a superstring theory based on the quadratically nonlinear SO(N)-extended superconformal algebra. In the realization of the algebra that we use, all the physical states are discrete, analogous to the situation in a one-scalar bosonic string. The BRST operator for the N = 3 case needs to be treated separately, and its construction is given here.
