Very Long Baseline Neutrino Oscillations, The BNL VLBNLO Concept

TL;DR

This paper discusses a proposed experiment using a wide energy-band neutrino beam over a very long baseline to precisely measure neutrino oscillation parameters, determine the mass hierarchy, and potentially observe CP violation.

Contribution

It introduces the BNL VLBNLO concept, a novel experimental setup designed to resolve degeneracies in neutrino oscillation parameters and measure CP violation with a single neutrino beam.

Findings

Potential to measure disappearance parameters with high precision

Ability to determine the neutrino mass hierarchy

Possibility to measure CP violation if θ13 is large enough

Abstract

A wide energy-band neutrino beam sent over a very long baseline to a massive detector can break the degeneracies in the neutrino oscillation parameters. It can measure the disappearance parameters with precision and determine the mass hierarchy. If $\theta_{13}$ is large enough the CP violating phase can be measured with neutrino running alone and anti-neutrino running can confirm CPV and improve the parameter measurements. Brookhaven National Laboratory is pursuing such an experiment.
