Abstract: The fermionic Neveu–Schwartz–Ramond string has a hidden $N=2$ superconformal symmetry on the worldsheet. Using an isomorphism of the $N=2$ superconformal algebra, we show how to obtain a subspace of physical string states on which the super-Poincaré group acts. The proposed construction is an alternative to the GSO projection in string theory.

Keywords: string theory, conformal field theory.
