Geometrical Constraints On Leptonic Unitarity Triangles

Abstract

The precision of the neutrino oscillation parameters measurements has improved and will continue to improve as the next-generation experiments become online. Beyond the more precise measurements of the mixing angles and phases used to parametrize the lepton mixing matrix, tests of its unitarity are of great interest. This paper studies how the amplitudes of the oscillation patterns can be used and combined to construct leptonic unitarity triangles.
