Impact of Inert Higgsino Dark Matter
Mayumi Aoki, Jisuke Kubo, Taishi Okawa +1
We consider a recently proposed supersymmetric radiative seesaw model which is coupled with the minimal supergravity. The conventional R parity and invariance are imposed, wh…
Testing the Higgs triplet model with the mass difference at the LHC
Mayumi Aoki, Shinya Kanemura, Kei Yagyu
In general, there can be mass differences among scalar bosons of the Higgs triplet field with the hypercharge of Y=1. In the Higgs triplet model, when the vacuum expectation value…
Decoupling property of the supersymmetric Higgs sector with four doublets
Mayumi Aoki, Shinya Kanemura, Tetsuo Shindou +1
In supersymmetric standard models with multi Higgs doublet fields, selfcoupling constants in the Higgs potential come only from the D-terms at the tree level. We investigate the de…
X(3872) and Its Iso-Triplet Partners
Kunihiko Terasaki
Decays of X(3872) and its partners as hidden-charm axial-vector tetra-quark mesons are studied. As the result, it is seen that the iso-triplet partners of X(3872) can be broad, and…
Two Component Dark Matters in S_4 x Z_2 Flavor Symmetric Extra U(1) Model
Yasuhiro Daikoku, Hiroshi Okada, Takashi Toma
We study cosmic-ray anomaly observed by PAMELA based on E_6 inspired extra U(1) model with S_4 x Z_2 flavor symmetry. In our model, the lightest flavon has very long lifetime of O(…
Doubly-charged scalar bosons from the doublet
Mayumi Aoki, Shinya Kanemura, Kei Yagyu
We consider the extended Higgs models, in which one of the isospin doublet scalar fields carries the hypercharge Y=3/2. Such a doublet field is composed of a doubly charg…
Light Charged Higgs bosons at the LHC in 2HDMs
Mayumi Aoki, Renato Guedes, Shinya Kanemura +3
We present a discussion of light charged Higgs boson searches at the Large Hadron Collider (LHC) in CP-conserving 2-Higgs Doublet Models (2HDMs). Taking into account all available…
Direct and Indirect Detection of Dark Matter in D6 Flavor Symmetric Model
Yuji Kajiyama, Hiroshi Okada, Takashi Toma
We study a fermionic dark matter in a non-supersymmetric extension of the standard model with a family symmetry based on D6xZ2xZ2. In our model, the final state of the dark matter…
Variations on the Supersymmetric Q6 Model of Flavor
K. S. Babu, Kenji Kawashima, Jisuke Kubo
We observe that a recently proposed supersymmetric model with Q6 flavor symmetry admits a new CP violating ground state. A new sum rule for the quark mixing parameters emerges, whi…
Affleck-Dine leptogenesis in the radiative neutrino mass model
H. Higashi, T. Ishima, D. Suematsu
Radiative neutrino mass models have interesting features, which make it possible to relate neutrino masses to the existence of dark matter. However, the explanation of the baryon n…
Thermal leptogenesis in a TeV scale model for neutrino masses
Daijiro Suematsu
It is known that the radiative neutrino mass model proposed by Ma could be a consistent framework for dark matter, leptogenesis and suppressed lepton flavor violation if a neutral…
Triviality and vacuum stability bounds in the three-loop neutrino mass model
Mayumi Aoki, Shinya Kanemura, Kei Yagyu
We study theoretical constraints on the parameter space under the conditions from vacuum stability and triviality in the three-loop radiative seesaw model with TeV-scale right-hand…
Right-handed Sneutrino Dark Matter in Supersymmetric B-L Model
Shaaban Khalil, Hiroshi Okada, Takashi Toma
We show that the lightest right-handed sneutrino in TeV scale supersymmetric B-L model with inverse seesaw mechanism is a viable candidate for cold dark matter. We find that it acc…
