Leptogenesis in the littlest inverse seesaw model

Yan Shao, Zhen-hua Zhao, Yi-Fei Duan

The littlest inverse seesaw (LIS) model represents the first low-scale seesaw framework to successfully account for all six physical observables of the neutrino sector with merely…

Leptogenesis implications of two-zero textures of Majorana neutrino mass matrix in type-I seesaw model

Xin-Tong Ma, Ding-Hui Xu, Zhen-hua Zhao

The type-I seesaw model with two-zero textures of the Majorana mass matrix for the right-handed neutrinos provides a highly predictive framework for neutrino mass ge…

Rescuing leptogenesis in inverse seesaw models with the help of non-Abelian flavor symmetries

Yan Shao, Zhen-hua Zhao

The inverse seesaw (ISS) model provides an attractive framework that can naturally explain the smallness of neutrino masses while accommodating some sterile neutrinos potentially a…

Renormalization group running triggered tri-resonant leptogenesis within neutrino flavor-symmetry models

Zhi-Cheng Liu, Zhen-hua Zhao

In this paper, we have studied the consequences of some representative neutrino flavor-symmetry models for tri-resonant leptogenesis (which is realized by having three nearly degen…

Linear seesaw leptogenesis before/after electroweak symmetry breaking

Yan Shao, Zhen-hua Zhao

The linear seesaw (LSS) model provides a natural framework for generating small neutrino masses at low energy scales, thereby offering promising testability prospects. However, in…

Low scale leptogenesis under neutrino - reflection symmetry

Yan Shao, Zhen-hua Zhao

In the literature, the neutrino - reflection symmetry (which has the interesting predictions and for the atmospherical neutrino mixing ang…
