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…
