Abstract
The analytical expression for the vacuum polarization coefficient a3 i s obtained from the on-shell Callan-Symanzik function beta4 given by B roadhurst, Kataev and Tarasov. These expressions for beta4 and a3 are found to be consistent with the expression for the Gell-Mann-Low funct ion PSI4 given by Gorishny, Kataev, Larin and Surguladze.
