TL;DR

This paper explores the potential of a high-energy beta beam from CERN to Pyh"asalmi Mine, combined with a conventional beam, to improve measurements of neutrino oscillation parameters, especially for small  mixing angles.

Contribution

It introduces a novel experimental setup combining a high-Q beta beam with a conventional beam over a long baseline for enhanced neutrino parameter sensitivity.

Findings

Effective measurement of neutrino parameters for  ^{-3}

Demonstrates the power of combined beam approach

Long baseline enhances oscillation sensitivity

Abstract

I consider a high-Q beta beam peaking at multi-GeV energy for the baseline CERN-Pyh\"asalmi, with the length of 2288 km, using LENA, a 50 kton liquid scintillator as the far detector. The beta beam is assumed to be accompanied by a conventional wide band beam of 1--6 GeV. This combination turns out to be very powerful to measure neutrino parameters if $\sin^2 2\theta_{13}\sim (1...3)\cdot 10^{-3}$.
