General Quartic β-Function at Three Loops
Abstract
We determine the three-loop MS quartic β -function for the most general renormalisable four-dimensional theories. A general parametrization of the β -function is compared to known β -functions for specific theories to fix all coefficients. Three-loop β -functions for the cubic coupling and scalar mass terms also follow from the result, which is made available in software packages.
