We study the ultraviolet stability problem for the two-dimensional Yukawa interaction $\lambda\int :\cos\alpha\varphi_\xi: d\xi$ in the region $4\pi<\alpha^2<\bar\alpha^2$ where $6\pi<\bar\alpha^2<8\pi$. The results have a natural Coulomb gas, interpretation, because the counterterms do not depend on the field.

Abstract
We study the ultraviolet stability problem for the two-dimensional Yukawa interaction $\lambda\int :\cos\alpha\varphi_\xi: d\xi$ in the region $4\pi<\alpha^2<\bar\alpha^2$ where $6\pi<\bar\alpha^2<8\pi$. The results have a natural Coulomb gas, interpretation, because the counterterms do not depend on the field.File allegati a questo prodotto
