TL;DR
This paper extends a superstring quantization method to different superstring types, showing both are anomaly-free and Poincare invariant, with implications for 4D supergravity analogies.
Contribution
It generalizes the Polchinski-Strominger quantization approach to superstrings, analyzing Ramond-Neveu-Schwarz and Green-Schwarz strings in non-critical dimensions.
Findings
Both superstring types are anomaly-free.
Both maintain Poincare invariance.
Formal analogy with 4D supergravity is discussed.
Abstract
We generalize the method of quantizing effective strings proposed by Polchinski and Strominger to superstrings. The Ramond-Neveu-Schwarz string is different from the Green-Schwarz string in non-critical dimensions. Both are anomaly-free and Poincare invariant. Some implications of the results are discussed. The formal analogy with 4D (super)gravity is pointed out.
