# Matter density profile effects on neutrino oscillations at T2HK and T2HKK

## TL;DR

This study investigates how variations in matter density profiles influence neutrino oscillations and assesses the detectability of these effects in the upcoming T2HK and T2HKK experiments.

## Contribution

It introduces an analysis of matter density profile effects on neutrino oscillations specifically for the T2HK and T2HKK experiments, including the potential impact of a second detector in Korea.

## Key findings

- Matter density variations can significantly affect neutrino oscillation measurements.
- The T2HKK setup enhances sensitivity to matter density effects.
- Potential to improve understanding of Earth's interior through neutrino experiments.

## Abstract

This project aims to explore the effects that changes in a matter density profile could have on neutrino oscillations, and whether these could potentially be seen by the future Hyper-Kamiokande experiment (T2HK). The analysis is extended to include the possibility of having a second detector in Korea (T2HKK).
