A Way To Improve the String Tension Dependence on Temperature in Holographic Model

The string tension dependence on temperature is studied in a five-dimensional anisotropic holographic model for light quarks. This model generalizes the isotropic holographic model with light quarks and is supported by Einstein-dilaton-two-Maxwell action. The asymptotics of the Cornell potential at large distances strongly depend on the parameter of anisotropy and orientation. There is also a nontrivial dependence of the Cornell potential on the boundary conditions of the dilaton field. With the help of modified boundary conditions for the dilaton field the results of the lattice calculations for the string tension are fitted as a function of temperature.
