Field theory actions for ambitwistor string and superstring
arXiv:1807.07661 · doi:10.1007/JHEP09(2018)097
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.
