BFT embedding of the Green-Schwarz superstring and the pure spinor formalism

TL;DR

This paper applies the BFT conversion to the Green-Schwarz superstring, successfully relating it to the pure spinor formalism through a systematic gauge system construction.

Contribution

It introduces a BFT conversion method for the GS superstring constraints, establishing an explicit connection to the pure spinor formalism.

Findings

Successfully converted second class constraints to first class

Derived a gauge system equivalent to Berkovits and Marchioro's model

Bridged the GS superstring and pure spinor formalisms

Abstract

We worked out the Batalin-Fradkin-Tyutin (BFT) conversion program of second class constraints to first class constraints in the GS superstring using light cone coordinates. By applying this systematic procedure we were able to obtain a gauge system that is equivalent to the recent model proposed by Berkovits and Marchioro to relate the GS superstring to the pure spinor formalism.
