Magic Baseline Beta Beam

TL;DR

This paper evaluates the potential of a neutrino experiment using a beta-beam source at CERN and a large detector at INO, leveraging the 'magic' baseline to improve measurements of neutrino properties.

Contribution

It introduces a novel experimental setup combining CERN's beta-beam with INO's ICAL detector at the magic baseline for enhanced neutrino parameter determination.

Findings

Improved sensitivity to neutrino mass hierarchy.

Enhanced measurement accuracy of b8_{13}.

Potential to resolve parameter degeneracies.

Abstract

We study the physics reach of an experiment where neutrinos produced in a beta-beam facility at CERN are observed in a large magnetized iron calorimeter (ICAL) at the India-based Neutrino Observatory (INO). The CERN-INO distance is close to the so-called "magic" baseline which helps evade some of the parameter degeneracies and allows for a better measurement of the neutrino mass hierarchy and $\theta_{13}$.
