Infrared divergences in theories with massless scalar and spinor fields
A. Yu. Kamenshchik, N. A. Sveshnikov
Abstract:
It is shown that the matrix elements in the $\varphi^4$ and Wess–Zumino models are free of infrared divergences (except for the divergences in the propagator insertions in external lines). A class of models with massless spinor and scalar fields that possess an analogous infrared structure is found. The results are interpreted physically.
