Model of hard sphere system is important part of modern theories of liquids.Radial distribution function of hard sphere fluid represented in form ofexplicit analytical expression allows to obtain thermodynamic potentials inanalytical form, which is very helpful for further analysis and applications. Anew analytical expression of radial distribution function of hard sphere fluidis developed. The density derivative of the radial distribution function andthe first two terms of Barker-Henderson perturbation theory are derived asanalytical expressions. The obtained results agree well with publishedsimulation data. These results have important implications for real fluidmodeling using density functional theory and perturbation theories.
