Why a NESSiE-like experiment at SBL is needed?

TL;DR

The paper advocates for a NESSiE-like experiment at SBL to precisely measure muon-neutrino disappearance, aiming to resolve anomalies and explore sterile neutrino models at short baselines.

Contribution

It proposes a new experimental setup at SBL with magnetic spectrometers to conclusively test sterile neutrino oscillations and address existing neutrino anomalies.

Findings

Demonstrates the experiment's potential to resolve muon-neutrino disappearance anomalies.

Shows the experiment can explore mixing angles at an unprecedented sensitivity.

Argues the setup is the most robust and rapid approach for neutrino physics at these scales.

Abstract

The NESSiE experiment is designed to perform an accurate measurement of muon-neutrino disappearance at small L/E, in order to severely constrain models with more than three-standard neutrinos, or even determine for the first time the presence of a new kind of neutrino oscillation. NESSiE is a Short-Baseline experiment with magnetic spectrometers at two different sites on the FNAL-Booster neutrino beam. The experiment would allow to definitively solve the existing tension of the muon-neutrino disappearance result with the appearance and disappearance "anomalies" at eV mass scale, by spanning one more order of magnitude in the mixing angle between standard and sterile neutrinos. We demonstrate that this project constitutes the most robust and fast way to unambigously study the neutrino physics at that scales.
