A.V. Bednyakov, A.F. Pikelner
TL;DR
This paper computes the four-loop beta-function of the strong coupling in the Standard Model, incorporating top-Yukawa and Higgs interactions while neglecting electroweak effects, advancing precision in theoretical predictions.
Contribution
It provides the first four-loop calculation of the strong coupling beta-function in the Standard Model including top-Yukawa and Higgs interactions.
Findings
Four-loop beta-function derived for the strong coupling.
Includes top-Yukawa and Higgs interactions in the calculation.
Electroweak gauge couplings are neglected in this analysis.
Abstract
In this letter we present our results for the four-loop beta-function of the strong coupling in the Standard Model of fundamental interactions. We take top-Yukawa and self-Higgs interactions into account, but neglect electroweak gauge couplings.
