Augmented recursion for one-loop gravity amplitudes

We present a semi-recursive method for calculating the rational parts of one-loop gravity amplitudes which utilises axial gauge diagrams to determine the nonfactorising pieces of the amplitude. This method is used to compute the amplitudes M 1-loop (1 − , 2 + , 3 + , 4 + , 5 + ) and M 1-loop (1 − ,...

Summary:We present a semi-recursive method for calculating the rational parts of one-loop gravity amplitudes which utilises axial gauge diagrams to determine the nonfactorising pieces of the amplitude. This method is used to compute the amplitudes M 1-loop (1 − , 2 + , 3 + , 4 + , 5 + ) and M 1-loop (1 − , 2 + , 3 + , 4 + , 5 + , 6 + ).
