We analyse one-loop graviton amplitudes in the field theory limit of a genus-one string theory computation. The considered amplitudes can be dimensionally reduced to lower dimensions preserving maximal supersymmetry. The particular case of the one-loop fivegraviton amplitude is worked out in detail and explicitly features no triangle contributions. Based on… CONTINUE READING
