Four-loop approximation in the $\varphi^4$ model

F. M. Dittes, Yu. A. Kubyshin, O. V. Tarasov


Abstract: The results are given of calculations of the Gelt-Mann–Low function in the four-loop approximation in the massless model with quartic interaction. The coefficients in the expansion of the Gell-Mann–Low function calculated in the framework of perturbation theory are compared with the coefficients calculated in accordance with the asymptotic formula.
