Phenomenological constraints on minimally coupled exotic lepton triplets
Chun-Khiang Chua, Sandy S. C. Law
By introducing a set of new triplet leptons (with nonzero hypercharge) that can Yukawa couple to their Standard Model counterparts, new sources of tree-level flavor changing curren…
Neutrino Models and Leptogenesis
Sandy S. C. Law
Neutrino properties can play a crucial role in determining the matter-antimatter asymmetry of the universe if thermal leptogenesis is the correct solution to the baryogenesis probl…
Electromagnetic Leptogenesis
Nicole F. Bell, Boris J. Kayser, Sandy S. C. Law
We present a new leptogenesis scenario, where the lepton asymmetry is generated by CP violating decays of heavy electroweak singlet neutrinos via electromagnetic dipole moment coup…
Leptogenesis implications in models with Abelian family symmetry and one extra real Higgs singlet
Sandy S. C. Law, Raymond R. Volkas
We show that the neutrino models, as suggested by Low, which have an additional Abelian family symmetry and a real Higgs singlet to the default see-saw do not hinder the possibilit…
