# Does the Wolfenstein form work for the leptonic mixing matrix?

## TL;DR

This paper demonstrates that the Wolfenstein parametrization, when evolved through renormalization group equations, can naturally lead to the large leptonic mixing observed at low energies.

## Contribution

It shows that the Wolfenstein form for the leptonic mixing matrix evolves under renormalization group flow to match experimental observations.

## Key findings

- Renormalization group evolution transforms the Wolfenstein form into observed large mixing.
- The approach provides a theoretical link between high-energy parametrization and low-energy data.
- Supports the Wolfenstein form as a viable initial condition for leptonic mixing models.

## Abstract

Starting with the Wolfenstein form for the leptonic mixing matrix we show that renormaliztion group evolution brings that to the observed large mixing at low energies.
