Nonzero U_{e3}, CP violation and leptogenesis in a see-saw type softly broken A_4 symmetric model

Biswajit Adhikary, Ambar Ghosal

We have shown that non-zero U_{e3} is generated in a see-saw type softly broken A_4 symmetric model through a single parameter perturbation in m_D in a single element. We have expl…
