Majoron Dark Energy via Freezing Induced by Quantum Coherence
Keunsu Cheon, Sin Kyu Kang, Jungjai Lee
We propose a nonequilibrium mechanism for Majoron dark energy in which the late-time freezing of a physical Majoron is induced by quantum coherence in a hidden pseudo-Dirac sterile…
Simple Modular invariant model for Quark, Lepton, and flavored-QCD axion
Y. H. Ahn, Sin Kyu Kang
We propose a minimal extension of the Standard Model by incorporating sterile neutrinos and a QCD axion to account for the mass and mixing hierarchies of quarks and leptons and to…
Disentangling the high and low cutoff scales via the trilinear Higgs couplings in the type-I two-Higgs-doublet model
Sin Kyu Kang, Jinheung Kim, Soojin Lee +1
The type-I two-Higgs-doublet model in the inverted Higgs scenario can retain the theoretical stability all the way up to the Planck scale. The Planck-cutoff scale, $Λ_{\rm cut}^{\r…
Confronting the prediction of leptonic Dirac CP-violating phase with experiments
Yang Hwan Ahn, Sin Kyu Kang, Raymundo Ramos +1
We update and improve past efforts to predict the leptonic Dirac CP-violating phase with models that predict perturbatively modified tribimaximal or bimaximal mixing. Simple pertur…
Implications of the new CDF-II -boson mass on two-Higgs-doublet models
Yang Hwan Ahn, Sin Kyu Kang, Raymundo Ramos
We present the implications of the recent measurement of boson at CDF II on the two-Higgs-doublet model (2HDM). In the analysis, we impose theoretical bounds such as vacuum sta…
Towards a Model of Quarks and Leptons
Y. H. Ahn, Sin Kyu Kang, Hyun Min Lee
We propose an extra-dimension framework on the orbifold for understanding the origin of the fermion mass and mixing hierarchies. Introducing the flavor symmetry {\…
