„A solvable non-trivial QFT in 4 dimensions“
Abstract:
A 4 dim. QFT needs regularization and renormalization.
I first discribe these concepts. We mention the UV, the IR and the Landau ghost problem.
Next we turn to the formulation of a noncommutative QFT, which becomes renormalizable
after identifying a fourth relevant/marginal operator. The beta function of the coupling
constant vanishes and a nonperturbative construction was possible and will be explained.
The model is nontrivial and all Schwinger functions are obtained from the solution of a
nonlinear integral equation.
