The Superembedding Origin of the Berkovits Pure Spinor Covariant Quantization of Superstrings

Marco Matone, Luca Mazzucato, Ichiro Oda +2

We show that the pure spinor formalism proposed by Berkovits to covariantly quantize superstrings is a gauge fixed, twisted version of the complexified n=2 superembedding formulati…
