WebAug 11, 2024 · 14.4: Optical Theorem. because P l ( 0) = 1 . This result is known as the optical theorem , and is a consequence of the fact that the very existence of scattering requires scattering in the forward ( θ = 0) direction, in order to interfere with the incident wave, and thereby reduce the probability current in that direction.

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. chipotle fridley

In physics, the optical theorem is a general law of wave scattering theory, which relates the forward scattering amplitude to the total cross section of the scatterer. It is usually written in the form where f(0) is the scattering amplitude with an angle of zero, that is the amplitude of the wave scattered to the center of a distant screen and k is the wave vector in the incident direction.
