Resolving Octant Degeneracy at LBL experiment by combining Daya Bay Reactor Setup

TL;DR

This paper demonstrates that combining Daya Bay Reactor data with long baseline experiments can effectively resolve the Octant degeneracy issue, enhancing the precision of neutrino parameter measurements.

Contribution

It introduces a novel approach of integrating Daya Bay data with LBL experiments to fully resolve the Octant degeneracy problem.

Findings

Octant degeneracy exists in LBL experiments.

Combining Daya Bay data can resolve degeneracy at various CP phases.

Complete resolution of degeneracy in LBNE achieved.

Abstract

Long baseline Experiment (LBL) have promised to be a very powerful experimental set up to study various issues related to Neutrinos. Some ongoing and planned LBL and medium baseline experiments are - T2K, MINOS, NOvA, LBNE, LBNO etc. But the long baseline experiments are crippled due to presence of some parameter degeneracies, like the Octant degeneracy. In this work, we first show the presence of Octant degeneracy in LBL experiments, and then combine it with Daya Bay Reactor experiment, at different values of CP violation phase. We show that the Octant degeneracy in LBNE can be resolved completely with this proposal.
