| contents | This work considers a variation of the massive ambitwistor string model presented in arXiv:2301.11227 that describes supergravity and super-Yang-Mills on the Coulomb branch simultaneously with a single Lagrangian. All-multiplicity tree and one-loop amplitudes are evaluated and shown to have proper unitary factorization. The massless limit provides Einstein Yang-Mills Amplitudes including multiple gluon traces. It is argued that the cosmological constant vanishes at all orders of perturbation theory. As application, results for Compton scattering are obtained and compared with ones in the literature. |
