Description

Gorishny et al. have recently calculated the four-loop corrections to the QED Callan-Symanzik Beta-function and the Gell-Mann-Low function psi. We have verified their result by explicitly checking that psi satisfies the Gell-Man-Low equation and in doing so have calculated the fifth-order vacuum polarization coefficient b5.
