    • Although well known it is nevertheless worthwhile reminding ourselves how the self-energy is related to a dissipative term in a field equation. A wave of small amplitude evolves in time according to the pole of its propagator, which is determined by the zeros of (Formula presented) where (Formula presented) is the retarded self-energy. Generally Π has both real and imaginary parts. Defining (Formula presented) where (Formula presented) is the real part of the pole, one finds that the wave decays like (Formula presented) The origin of the factor of 2 is that Γ represents the loss rate for the number density whereas Γ/2 is the rate for the amplitude. See, for example, H. A. Weldon, Phys. Rev. D 28, 2007 (1983). This physics may be represented in a real Klein-Gordon wave equation by the dissipative term (Formula presented)
