# Short- and long-baseline sterile neutrino phenomenology

## TL;DR

This paper reviews the current status of sterile neutrino phenomenology within the 3+1 framework, highlighting the role of long-baseline experiments in exploring CP violation and complementing short-baseline searches.

## Contribution

It provides a concise overview of sterile neutrino phenomenology and emphasizes the importance of combining long- and short-baseline experiments for comprehensive exploration.

## Key findings

- Sterile neutrinos could explain anomalies in short-baseline experiments.
- Long-baseline experiments have potential to detect CP violation related to sterile neutrinos.
- The 3+1 scheme is a minimal extension of the standard neutrino model.

## Abstract

Several anomalies observed in short-baseline neutrino experiments indicate that the standard 3-flavor framework may be incomplete and point towards the existence of light sterile neutrinos. Here, we present a concise review of the status of the neutrino oscillations within the 3+1 scheme, which is a minimal extension of the standard 3-flavor framework with one sterile neutrino species. We emphasize the potential role of LBL experiments in the searches of CP violation connected to sterile neutrinos and their complementarity with the SBL experiments.
