31 Jan 2017 | | Abstract: | The leptonic CP (Dirac) phase $delta_{CP}$ is now the most crucial unknown
parameter in neutrino oscillation physics. While there are hints for a
preferred quadrant for this parameter, its determination is dependent on the
equally unknown mass ordering of the neutrinos. In this paper we show through a
simple analytical analysis that this CP phase may be determined using low
energy atmospheric neutrino data almost unambigiously, {em independent} of the
ordering of masses and almost independent of the angle $ heta_{23}$ octant
ambiguities. While sensitivity is maximum when the neutrino and antineutrino
samples can be distinguished, we also demonstrate this sensitivity through a
comparison with present Super-Kamiokande data. | | Source: | arXiv, 1701.8997 | | Services: | Forum | Review | PDF | Favorites | |
