Snowmass Topical Report: Underground Facilities for Neutrinos

TL;DR

This report reviews the underground facility requirements for future neutrino research, covering accelerator-based experiments like DUNE and natural source studies, including neutrinoless double-beta decay searches.

Contribution

It provides a comprehensive overview of underground infrastructure needs for next-generation neutrino experiments, integrating both accelerator and non-accelerator research contexts.

Findings

Identifies key underground facility requirements for DUNE and other experiments.

Highlights the importance of underground labs for neutrinoless double-beta decay.

Summarizes current and future infrastructure needs for neutrino physics.

Abstract

This topical report of the 2021 US Community Study on the Future of Particle Physics (Snowmass 2021) summarizes the underground facilities needs for upcoming and next generation neutrino experiments. The underground facilities needs are discussed in the context of two broad categories: accelerator neutrinos, in particular with respect to the Deep Underground Neutrino Experiment (DUNE); and non-accelerator neutrinos, focusing on neutrinos from natural sources and on searches for neutrinoless double-beta decay.
