The generalized no-ghost theorem for N=2 SUSY critical strings
Abstract
We prove the no-ghost theorem for the N=2 SUSY strings in (2, 2) dimensional flat Minkowski space. We propose a generalization of this theorem for an arbitrary geometry of the N=2 SUSY string theory taking advantage of the N=4 SCA generators present in this model. Physical states are found to be the highest weight states of the N=4 SCA.
