Title: | Ambitwistor string vertex operators on curved backgrounds |
Authors: | Adamo, T Casali, E Nekovar, S |
Item Type: | Journal Article |
Abstract: | We present vertex operators for ambitwistor strings around generic Yang-Mills, gravity and NS-NS backgrounds. The requirement that vertex operators lie in the BRST cohomology of the worldsheet theory enforces the appropriate linear equations of motion (as well as gauge fixing conditions) for the respective perturbations in these backgrounds. Due to the nature of ambitwistor strings, no approximation is taken and all calculations around the backgrounds are exact. |
