Semi-aligned two Higgs doublet model

Naoyuki Haba, Hiroyuki Umeeda, Toshifumi Yamada

In the left-right symmetric model based on $S U (2)_{L} \times S U (2)_{R} \times U (1)_{B - L}$ gauge symmetry, there appear heavy neutral scalar particles mediating quark flavor changing neut…

Phenomenological Aspects of Possible Vacua of a Neutrino Flavor Model

Takuya Morozumi, Hideaki Okane, Hiroki Sakamoto +3

We discuss a supersymmetric model with discrete flavor symmetry $A_{4} \times Z_{3}$ . The additional scalar fields which contribute masses of leptons in the Yukawa terms are introduced…
