Stable Bimaximal neutrino mixing pattern

TL;DR

This paper explores whether a specific neutrino mixing pattern with two large angles and one small angle can naturally arise as a fixed point through renormalisation group evolution, shedding light on its theoretical origin.

Contribution

It investigates the possibility of generating the bimaximal neutrino mixing pattern as a fixed point of renormalisation group evolution, providing insights into its theoretical basis.

Findings

Potential fixed point of RG evolution identified for the mixing pattern.

Implications for neutrino mass models and mixing angles.

Constraints on model parameters for pattern stability.

Abstract

The neutrino oscillation experiments increasingly point towards a mixing pattern that can be parametrised with two near maximal and one small mixing angle. We investigate whether such a mixing pattern can be generated as a fixed point of renormalisation group evolution.
