Electroweak and Conformal Symmetry Breaking by a Strongly Coupled Hidden Sector
Martin Holthausen, Jisuke Kubo, Kher Sham Lim +1
The LHC and other experiments show so far no sign of new physics and long-held beliefs about naturalness should be critically reexamined. We discuss therefore in this paper a model…
Phenomenology of S_4 Flavor Symmetric extra U(1) model
Yasuhiro Daikoku, Hiroshi Okada
We study several phenomenologies of an E_6 inspired extra U(1) model with S_4 flavor symmetry. With the assignment of left-handed quarks and leptons to S_4-doublet, SUSY flavor pro…
Reconstruction of Inert Doublet Scalars at the International Linear Collider
Mayumi Aoki, Shinya Kanemura, Hiroshi Yokoya
We study collider signatures for extra scalar bosons in the inert doublet model at the international linear collider (ILC). The inert doublet model is a simple extension of the sta…
Two-loop radiative seesaw with multicomponent dark matter explaining the possible gamma excess in the Higgs boson decay and at the Fermi LAT
Mayumi Aoki, Jisuke Kubo, Hiroshi Takano
A non-supersymmetric model of a two-loop radiative seesaw is proposed. The model contains, in addition to the standard model (SM) Higgs boson, an inert SU(2)_L doublet scalar eta a…
Leptogenesis and dark matter detection in a TeV scale neutrino mass model with inverted mass hierarchy
Shoichi Kashiwase, Daijiro Suematsu
Realization of the inverted hierarchy is studied in the radiative neutrino mass model with an additional doublet, in which neutrino masses and dark matter could be induced from a c…
