μ-τ reflection symmetry embedded in minimal seesaw
We embed μ - τ reflection symmetry into the minimal seesaw formalism, where two right-handed neutrinos are added to the Standard Model of particle physics. Assuming that both the left- and right-handed neutrino fields transform under μ - τ reflection symmetry, we obtain the required forms of the neu...
