On-Shell Covariance of Quantum Field Theory Amplitudes
Scattering amplitudes in quantum field theory are independent of the field parametrization, which has a natural geometric interpretation as a form of “coordinate invariance.” Amplitudes can be expressed in terms of Riemannian curvature tensors, which makes the covariance of amplitudes under nonderiv...
