Abstract

We apply the Padé summation to the (Formula presented) function for the quartic Higgs coupling (Formula presented) in the standard electroweak model. We use the (Formula presented) function calculated to five loops in the minimal subtraction scheme to demonstrate the improvement resulting from the summation, and then apply the method to the more physical on-mass-shell renormalization scheme where (Formula presented) is known to three loops. We find that the apparent convergence of the perturbation series for (Formula presented) is significantly improved, and apply the result to the study of the running coupling (Formula presented)
