Sterile neutrinos in cosmology and how to find them in the lab

TL;DR

This paper explores the role of sterile neutrinos in solving key cosmological and particle physics puzzles, and discusses experimental approaches to detect them in laboratory settings.

Contribution

It proposes that sterile neutrinos could address multiple unresolved phenomena and reviews experimental strategies for their detection.

Findings

Sterile neutrinos could explain neutrino oscillations, dark matter, and baryon asymmetry.

Dedicated experiments can potentially confirm or exclude sterile neutrinos as solutions.

The paper outlines specific experimental methods for laboratory detection.

Abstract

A number of observed phenomena in high energy physics and cosmology lack their resolution within the Standard Model of particle physics. These puzzles include neutrino oscillations, baryon asymmetry of the universe and existence of dark matter. We discuss the suggestion that all these problems can be solved by new physics which exists only below the electroweak scale. The dedicated experiments that can confirm or rule out this possibility are discussed.
