Field theory actions for ambitwistor string and superstring

High Energy Physics - Theory 2018-10-17 v2

Abstract

We analyze the free ambitwistor string field theory action for the bosonic string, heterotic string and both GSO sectors of the Type II string. The spectrum contains non-unitary states and provides an interesting consistency test for one-loop ambitwistor string computations.
