Likewise, in quantum field theory the tree-level amplitudes are real, — at least for the elastic scattering in the forward direction, — but the loop corrections make for complex amplitudes. The reason for this behavior is the optical theorem (21), plus power-of-the-coupling counting in the perturbation theory. cummings french bulldogs
