Mapping theorem and Green functions in Yang-Mills theory

Abstract

It is shown how, starting froma mapping theoremrecently proved between massless quartic scalar field theory and Yang-Mills theory, both two-point functions and spectrum of the Yang-Mills theory can be obtained. These results compare very well with respect to lattice computations. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution- NonCommercial-ShareAlike Licence.
