TL;DR
This paper proposes a short-baseline experiment at FNAL using magnetic spectrometers to search for sterile neutrinos via muon neutrino disappearance, aiming to significantly improve sensitivity over existing methods.
Contribution
It introduces a novel experimental setup with OPERA-like spectrometers at two sites, designed to enhance sensitivity to sterile neutrinos in the eV mass scale beyond current proposals.
Findings
Potential to extend sensitivity to neutrino mixing angles by over an order of magnitude.
Experimental design compatible with existing hardware and multi-site Liquid--Argon detectors.
Clarifies the tension between muon neutrino disappearance and electron neutrino anomalies.
Abstract
The NESSiE Collaboration has been setup to undertake a conclusive experiment to clarify the {\em muon--neutrino disappearance} measurements at short baselines in order to put severe constraints to models with more than the three--standard neutrinos. To this aim the current FNAL--Booster neutrino beam for a Short--Baseline experiment was carefully evaluated by considering the use of magnetic spectrometers at two sites, near and far ones. The detector locations were studied, together with the achievable performances of two OPERA--like spectrometers. The study was constrained by the availability of existing hardware and a time--schedule compatible with the undergoing project of multi--site Liquid--Argon detectors at FNAL. The settled physics case and the kind of proposed experiment on the Booster neutrino beam would definitively clarify the existing tension between the …
