# Seven largest couplings of the standard model as IR fixed points

## TL;DR

This paper explores how most Standard Model couplings, except for the first two generations, can be explained by infrared fixed points in the renormalization group equations within a minimal supersymmetric extension with an added vectorlike family.

## Contribution

It demonstrates that the IR fixed point structure in a specific supersymmetric model can account for the observed values of most Standard Model couplings.

## Key findings

- Most couplings align with IR fixed points in the model
- First two generation couplings are exceptions
- Provides a potential explanation for coupling values

## Abstract

We report on an intriguing observation that the values of all the couplings in the standard model except those related to first two generations can be understood from the IR fixed point structure of renormalization group equations in the minimal supersymmetric model extended by one complete vectorlike family with the scale of new physics in a multi-TeV range.
