Ternary Plots for Neutrino Mixing Visualization

TL;DR

This paper demonstrates how ternary plots can effectively visualize the neutrino mixing matrix, naturally incorporating unitarity constraints by representing three variables with a fixed sum within an equilateral triangle.

Contribution

It introduces the use of ternary plots for neutrino mixing visualization, highlighting their advantages in representing unitarity constraints naturally.

Findings

Ternary plots effectively visualize neutrino mixing matrices.

Unitarity constraints are automatically incorporated.

The method simplifies the interpretation of three-variable relationships.

Abstract

The visualization advantages of ternary plots are illustrated for the PMNS neutrino mixing matrix. Unitarity constraints are incorporated automatically, in part, since barycentric plots of this type allow three variables with a fixed sum to be plotted as mere points inside an equilateral triangle on a plane.
