Field theory actions for ambitwistor string and superstring

Journal of High Energy Physics, Sep 2018

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.
