Although covariant quantization is complicated by reducibility issues, a light-cone gauge analysis can be easily performed. We show that with this analysis, this supertwistor ambitwistor string is equivalent to the RNS ambitwistor string in light-cone gauge. In order to make the comparison, we develop the light-cone gauge analysis of the RNS ambitwistor string which has some novel features in terms of its expression of the scattering equations through interaction point operators.engBRST QuantizationConformal Field TheorySupergravity ModelsSuperstrings and Heterotic StringsArtigo10.1007/JHEP01(2020)0202-s2.0-85077610532
