Abstract
We discuss a novel alternative method of determining the neutrino mass ordering in medium baseline experiments with reactor antineutrinos. Results on the potential sensitivity of the new method are also presented.
Highlights
In the present article we consider a complementary method to the one proposed in [1] of determination of the neutrino mass ordering, i.e., the type of spectrum the neutrino masses obey, in medium baseline experiments with reactor antineutrinos [2]
Given the fact that, according to the current data, the best fit values of sin2 θ12 and cos2 θ12 differ by a factor of 2.3, and that sin2 θ12 is determined with a 1σ uncertainty of approximately 4.5%, the proposed method of determining the neutrino mass ordering seems feasible
In the present article we have investigated an alternative method of determination the type of spectrum neutrino masses obey in medium baseline experiments with reactor neutrinos
Summary
In the present article we consider a complementary method to the one proposed in [1] of determination of the neutrino mass ordering, i.e., the type of spectrum the neutrino masses obey, in medium baseline experiments with reactor antineutrinos [2]. A more general and detailed analysis performed in [21] revealed that a reactor neutrino experiment with a medium baseline tuned to achieve highest sensitivity in the determination of the neutrino mass ordering has a remarkable physics potential It was found, in particular, that for sin θ13 ∼> 0.02 it would be possible to measure in such an experiment i) sin θ12, ii) ∆m221 and iii) |∆m231(32)| with an exceptionally high precision. In addition of the potential to measure sin θ12, ∆m221 and |∆m231(32)| with remarkably high precision, these experiments can be used for detection and studies of geo, solar and supernovae neutrinos
