Interplay between Vector-like Lepton and Seesaw Mechanism:Oblique Corrections
Shuyang Han, Zhaofeng Kang, Jiang Zhu
The non-vanishing neutrino mass strongly hints the existence of right-handed neutrinos (RHNs), singlets of the standard model (SM). However, they are highly decoupled from the SM a…

A Light Lepton-flavor-violating Flavon: the Messenger of Neutrino Mixing and Muon
Shuyang Han, Zhaofeng Kang
In neutrino physics, a class of models with local or global family symmetries may be invoked, and then a flavon field is needed to realize the full neutrino mixing. This flavon may…
