Gauged breaking as origin of neutrino masses, dark matter and leptogenesis at TeV scale
Toshinori Matsui, Takaaki Nomura, Kei Yagyu
We propose a new mechanism which simultaneously explains tiny neutrino masses, stability of dark matter and baryon asymmetry of the Universe via leptogenesis due to the common orig…
Flavor Dependent Symmetric Zee Model with a Vector-like Lepton
Toshinori Matsui, Takaaki Nomura, Kei Yagyu
We extend the Zee model by introducing a vector-like lepton doublet and a flavor dependent global symmetry. Flavor changing neutral currents in the quark sector can be natur…
Dark Matter Bound State Formation in Fermionic DM model with Light Dark Photon and Dark Higgs Boson
Pyungwon Ko, Toshinori Matsui, Yi-Lei Tang
If fermionic dark matter (DM) is stabilized by dark gauge symmetry that is spontaneously broken into its subgroup , the particle contents of the model becomes very rich…
Exploring first order phase transition in extended models by complementarity between collider measurements and cosmological observations
Toshinori Matsui
We consider models with the gauge symmetry, which is spontaneously broken by dark Higgs mechanism. We discuss patterns of the electroweak phase transition and detectabilit…
Gravitational waves from first order electroweak phase transition in models with the gauge symmetry
Katsuya Hashino, Mitsuru Kakizaki, Shinya Kanemura +2
We consider a standard model extension equipped with a dark sector where the Abelian gauge symmetry is spontaneously broken by the dark Higgs mechanism. In this framewo…
Gravitational waves from the first order electroweak phase transition in the symmetric singlet scalar model
Toshinori Matsui
Among various scenarios of baryon asymmetry of the Universe, electroweak baryogenesis is directly connected with physics of the Higgs sector. We discuss spectra of gravitational wa…
Gravitational waves and Higgs boson couplings for exploring first order phase transition in the model with a singlet scalar field
Katsuya Hashino, Mitsuru Kakizaki, Shinya Kanemura +2
We calculate the spectrum of gravitational waves originated from strongly first order electroweak phase transition in the extended Higgs model with a real singlet field. In order t…
Synergy between measurements of the gravitational wave and the triple Higgs coupling in probing first order phase transition
Katsuya Hashino, Mitsuru Kakizaki, Shinya Kanemura +1
Probing the Higgs potential and new physics behind the electroweak symmetry breaking is one of the most important issues of particle physics. In particular, nature of electroweak p…
Gravitational waves as a probe of extended scalar sectors with the first order electroweak phase transition
Mitsuru Kakizaki, Shinya Kanemura, Toshinori Matsui
We discuss spectra of gravitational waves which are originated by the strongly first order phase transition at the electroweak symmetry breaking, which is required for a successful…
Neutrino Mass and Dark Matter from Gauged BL Breaking
Toshinori Matsui
We discuss a new radiative seesaw model with the gauged BL symmetry which is spontaneously broken. We improve the previous model by using the anomaly-free condition without intr…
Indirect reach of heavy MSSM Higgs bosons by precision measurements at future lepton colliders
Mitsuru Kakizaki, Shinya Kanemura, Mariko Kikuchi +2
In the Minimal Supersymmetric Standard Model (MSSM), the bottom Yukawa coupling of the Higgs boson can considerably deviate from its Standard Model prediction due to non-decoupling…
Higgs inflation scenario in a radiative seesaw model and its testability at the ILC
Toshinori Matsui
The Higgs inflation scenario is an approach to realize the cosmic inflation, where the Higgs boson plays a role of the inflaton. In the minimal model, it would be difficult to sati…
Neutrino Mass and Dark Matter from Gauged Breaking
Shinya Kanemura, Toshinori Matsui, Hiroaki Sugiyama
We propose a new model where the Dirac mass term for neutrinos, the Majorana mass term for right-handed neutrinos, and the other new fermion masses arise via the spontaneous breakd…
Loop Suppression of Dirac Neutrino Mass in the Neutrinophilic Two Higgs Doublet Model
Shinya Kanemura, Toshinori Matsui, Hiroaki Sugiyama
We extend the scalar sector of the neutrinophilic two Higgs doublet model, where small masses of Dirac neutrinos are obtained via a small vacuum expectation value v_nu of the neutr…
Testability of the Higgs inflation scenario in a radiative seesaw model
Toshinori Matsui
The Higgs inflation scenario is an approach to realize the inflation, in which the Higgs boson plays a role of the inflaton without introducing a new particle. We investigate a Hig…
Higgs inflation in a radiative seesaw model
Shinya Kanemura, Toshinori Matsui, Takehiro Nabeshima
We investigate a simple model to explain inflation, neutrino masses and dark matter simultaneously. This is based on the so-called radiative seesaw model proposed by Ma in order to…
