Covariant field theory for self-dual strings

TL;DR

This paper introduces a covariant field theory for self-dual strings that maintains SO(2,2) symmetry, using gauge connections to unify super-Virasoro generators with covariant derivatives.

Contribution

It presents a novel gauge and SO(2,2) covariant formulation of self-dual string theory, linking super-Virasoro generators with gauge connections.

Findings

Achieves manifest SO(2,2) covariance in self-dual string theory

Reformulates string fields as gauge connections

Unifies super-Virasoro generators with covariant derivatives

Abstract

We give a gauge and manifestly SO(2,2) covariant formulation of the field theory of the self-dual string. The string fields are gauge connections that turn the super-Virasoro generators into covariant derivatives.
