This project has received funding from the European Union’ s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement No 690575. This project has also received funding from the European Union’ s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement No 674896. The authors acknowledge the support of the Spanish MINECO Centro de Excelencia Severo Ochoa Programme under grant SEV-2012-0249. Each tree-level diagram workout in this paper has been computed in two independent ways, one using the computer algebra systems FORM [20] and the other Mathematica’s xAct [21] package.
dc.description.abstractThe maximally helicity violating tree-level scattering amplitudes involving three, four or five gravitons are worked out in Unimodular Gravity. They are found to coincide with the corresponding amplitudes in General Relativity. This a remarkable result, insofar as both the propagators and the vertices are quite different in the two theories.
