Off-shell Supersymmetry versus Hermiticity in the Superstring
arXiv:hep-th/9604121 · doi:10.1103/PhysRevLett.77.2891
Abstract
We point out that off-shell four-dimensional supersymmetry implies strange hermiticity properties for the N=1 RNS superstring. However, these hermiticity properties become natural when the N=1 superstring is embedded into an N=2 superstring.
