| contents | We construct several quantum gauge theories in 4 dimensional space time, including both Abelian and non Abelian gauge groups, with the Abelian gauge fields coupled to zero mass matter fields. The construction occurs in a fixed finite Euclidean spatial domain. The construction begins with the doubly cutoff bare field theory (with a finite space time volume and a mesh based ultraviolet cutoff) constructed in a separate paper.
We use a limited range of renormalized perturbation theory, just sufficient to cancel all the divergences. We demonstrate convergence of the ultraviolet limit and of the renormalized perturbation theory, when summed to all orders. We construct the fully renormalized Lagrangian and Schwinger functions. |
