Logarithmic correction in the deformed ${\mathrm{AdS}}_5$ model to produce the heavy quark potential and QCD beta function

Song He, Mei Huang, Qi-Shu Yan

We stude the \textit{holographic} QCD model which contains a quadratic term $-\sigma z^2$ and a logarithmic term $-c_0\log [(z_{IR}-z)/z_{IR}]$ with an explicit infrared cut-off $z_{IR}$…
