After adding non-minimal variables and working in the “large” Hilbert space, the algebra closes without picture-changing and spacetime supersymmetry can be made manifest. The resulting non-minimal version of the RNS formalism is related by a field redefinition to the pure spinor formalism.engSuperspacesSuperstrings and Heterotic StringsArtigo10.1007/JHEP10(2021)1622-s2.0-85117592917
