Abstract: Elaborating on the observation that two-particle unitarity-cuts of scatteringamplitudes can be computed by applying Stokes- Theorem, we relate the OpticalTheorem to the Berry Phase, showing how the imaginary part of arbitraryone-loop Feynman amplitudes can be interpreted as the flux of a complex 2-form.
