Abstract

We show that in a deformed AdS5{\rm AdS}_5 model with an explicit infrared cutoff included in the logarithmic correction c0log[(zIRz)/zIR]-c_0\log[(z_{IR}-z)/z_{IR}], the heavy quark Cornell potential can be fitted very well, the corresponding beta-function agrees with the QCD beta-function at 2-loop level reasonably well, and its dual dilaton potential is bounded from below in infrared. The results are compared with those in the Andreev-Zakharov model and the Pirner-Galow model.
