Query: $n$-point amplitudes with a single negative-helicity graviton   We construct an expression for the n-point one-loop graviton scattering
amplitude with a single negative helicity external leg using an augmented
recursion technique. We analyse the soft-limits of these amplitudes and
demonstrate that they have soft behaviour beyond the conjectured universal
behaviour.
