  • renormalization group analysis of the Hyperbolic Sine gordon model asymptotic freedom from cosh interaction
    Progress of Theoretical and Experimental Physics, 2019
    Co-Authors: Takashi Yanagisawa
    Abstract:

    We present a renormalization group analysis for the Hyperbolic Sine-Gordon (sinh-Gordon) model in two dimensions. We derive the renormalization group equations based on the dimensional regularization method and the Wilson method. The same equations are obtained using both these methods. We have two parameters $\alpha$ and $\beta\equiv \sqrt{t}$ where $\alpha$ indicates the strength of interaction of a real salar field and $t=\beta^2$ is related with the normalization of the action. We show that $\alpha$ is renormalized to zero in the high-energy region, that is, the sinh-Gordon theory is an asymptotically free theory. We also show a non-renormalization property that the beta function of $t$ vanishes in two dimensions.
