General gauge-Yukawa-quartic β-functions at 4-3-2-loop order

Abstract: We determine the full set of coefficients for the completely general 4-loop gauge and 3-loop Yukawa β-functions for the most general renormalizable four-dimensional theories. Using a complete parametrization of the β-functions, we compare the general form to the specific β-functions of known theories to constrain the unknown coefficients. The Weyl consistency conditions provide additional constraints, completing the determination.

“…RGBeta was originally developed to test the general β-function basis used and developed in Ref. [12] and is used in ongoing work on higher-order β-functions [16]. It is an implementation of the generally applicable MS β-function formulas for gauge-Yukawa theories presented in Ref.…”

“…[27]. The finite part of υ in the SM uniquely fixes two of the pure-Yukawa fermion coefficients: The Weyl consistency conditions derived from Osborn's Equation [27] with input from a (currently) partial reconstruction of the generic 4-3-2 β-functions [41], provides the independent constraint…”

“…While two-loop β-functions for the most general four-dimensional QFT have been known for almost four decades [6][7][8][9], higher orders only became available recently. The gauge coupling β-function for the most general QFT has been computed at three loops [10,11] and this year even the four-loop gauge coupling and threeloop Yukawa β-functions have become available [12,13].…”
