Renormalizable non-renormalizable theories
Hidenori Sonoda
The general prescription for constructing the continuum limit of a field theory is introduced. We then apply the prescription to construct the O(N) non-linear sigma model and the G…
Construction of a Wilson action for the Wess-Zumino model
Hidenori Sonoda, Kayhan Ulker
We construct a Wilson action for the Wess-Zumino model by applying the exact renormalization group perturbatively. Using neither superfields nor auxiliary fields, we construct a su…
The Exact Renormalization Group -- renormalization theory revisited --
Hidenori Sonoda
We overview the entire renormalization theory, both perturbative and non-perturbative, by the method of the exact renormalization group (ERG). We emphasize particularly on the pert…
Quantum Master Equation for QED in Exact Renormalization Group
Yuji Igarashi, Katsumi Itoh, Hidenori Sonoda
Recently, one of us (H.S.) gave an explicit form of the Ward-Takahashi identity for the Wilson action of QED. We first rederive the identity using a functional method. The identity…
On the construction of QED using ERG
Hidenori Sonoda
It has been known for some time that a smooth momentum cutoff is compatible with local gauge symmetries. In this paper we show concretely how to construct QED using the exact renor…
On the relation between RG and ERG
Hidenori Sonoda
We discuss how the ordinary renormalization group (RG) equations arise in the context of Wilson's exact renormalization group (ERG) as formulated by Polchinski. We consider the phi…
