Why is the neutrino mixing matrix almost unitary in realistic seesaw models?
Zhi-zhong Xing, Shun Zhou
A simple extension of the standard model is to introduce heavy right-handed Majorana neutrinos and preserve its gauge symmetry. Diagonalizing…

Possible Deviation from the Tri-bimaximal Neutrino Mixing in a Seesaw Model
Sin Kyu Kang, Zhi-zhong Xing, Shun Zhou
We propose a simple but suggestive seesaw model with two phenomenological conjectures: three heavy (right-handed) Majorana neutrinos are degenerate in mass in the symmetry limit an…
