# Matrix norms and search for sterile neutrinos

## TL;DR

This paper explores how various matrix norms can quantify deviations in neutrino mixing matrices, offering a new approach to measure sterile neutrino effects.

## Contribution

It introduces the use of different matrix norms to assess deviations in neutrino mixing matrices, providing a novel framework for sterile neutrino searches.

## Key findings

- Different matrix norms capture deviations at various structural levels.
- Matrix norms offer a versatile tool for analyzing neutrino mixing matrices.
- Potential to improve sterile neutrino detection methods.

## Abstract

Matrix norms can be used to measure the "distance" between two matrices which translates naturally to the problem of calculating the unitary deviation of the neutrino mixing matrices. Variety of matrix norms opens a possibility to measure such deviations on different structural levels of the mixing matrix.
