Purely flavon driven leptogenesis for exactly degenerate Dirac or Majorana neutrino mass matrix in the type-I seesaw model
Yan Shao, Zhen-hua Zhao
While the type-I seesaw model provides an attractive framework for simultaneously explaining the origin of neutrino masses and the baryon asymmetry of the Universe, flavor symmetri…
Rescuing flavor-symmetry-forbidden leptogenesis within the left-right symmetric framework
Yan Shao, Zhen-hua Zhao
While the type-I seesaw model provides a unified framework for explaining the origin of neutrino masses and the baryon asymmetry of the Universe, flavor symmetries offer an attract…
Flavon assisted low scale leptogenesis
Yan Shao, Zhen-hua Zhao
Low-scale leptogenesis scenarios, such as the resonant leptogenesis, typically require a highly degenerate mass spectrum of right-handed neutrinos (RHNs). This requirement can be c…
Neutrino mass anarchy and leptogenesis
Qi An, Yan Shao, Zhen-hua Zhao
In this paper, we investigate leptogenesis under the neutrino mass anarchy hypothesis in both type-I and type-II seesaw models. We first revisit the corresponding study in the type…
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…
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…
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…
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 angle and…
Consequences of the - reflection symmetry for leptogenesis in a seesaw model with diagonal Dirac neutrino mass matrix
Zhen-hua Zhao, Yan Shao, Hong-Yu Shi
In this paper, we have studied the consequences of the - reflection symmetry for leptogenesis in the type-I seesaw model with diagonal Dirac neutrino mass matrix. We have fir…
Leptogenesis consequences of trimaximal mixing and - reflection symmetry in the most minimal seesaw model
Zhen-hua Zhao, Hong-Yu Shi, Yan Shao
In this paper we have studied the realizations of the popular TM1 neutrino mixing and neutrino - reflection symmetry (which are well motivated from the neutrino oscillation d…
