Ambitwistor String Theory in the Operator Formalism

TL;DR

This paper develops an operator formalism for ambitwistor string theory, enabling the derivation of supergravity scattering amplitudes and exploring potential extensions to loop amplitudes and string field theory.

Contribution

It introduces a novel operator formalism for ambitwistor strings, connecting it with supergravity amplitudes and setting the stage for further theoretical developments.

Findings

Tree level supergravity amplitudes are recovered using the formalism

The formalism can be extended to loop amplitudes

Potential for constructing ambitwistor string field theory

Abstract

After a brief overview of the operator formalism for conventional string theory, an operator formalism for ambitwistor string theory is presented. It is shown how tree level supergravity scattering amplitudes are recovered in this formalism. More general applications of this formalism to loop amplitudes and the construction of an ambitwistor string field theory are briefly discussed.
