Unitarity Quadrangles of Four Neutrino Mixing

High Energy Physics - Phenomenology 2009-11-07 v4

Abstract

We present a classification of the unitarity quadrangles in the four-neutrino mixing scheme. We find that there are totally thirty-six distinct topologies among twelve different unitarity quadrangles. Concise relations are established between the areas of those unitarity quadrangles and the rephasing invariants of CP and TT violation.
