About testing nu_mu oscillation with Dm2 smaller than 0.001 eV2 with the CERN Proton Synchrotron

TL;DR

This paper evaluates the potential of a CERN to Gran Sasso neutrino experiment to explore small neutrino mass-squared differences below 0.001 eV^2, expanding the parameter space tested beyond previous experiments.

Contribution

It proposes a feasible long baseline neutrino experiment using CERN PS to probe new regions of neutrino oscillation parameters not covered by prior experiments.

Findings

Suitable baseline and energy spectrum identified for the experiment.

Potential to explore untested (Dm2, Sin2(theta)) parameter space.

Complementary to K2K and SuperKamiokande results.

Abstract

We study the feasibility of a long baseline neutrino experiment from CERN to Gran Sasso LNGS Laboratories using the CERN PS accelerator. Baseline and neutrino energy spectrum are suitable to explore a region of the (Dm2, Sin2(theta)) parameters space which is not reached by K2K, the first experiment that will test at accelerator the atmospheric neutrino anomaly put in evidence by SuperKamiokande.
