Scale genesis and gravitational wave in a classically scale invariant extension of the standard model

Jisuke Kubo, Masatoshi Yamada

We assume that the origin of the electroweak (EW) scale is a gauge-invariant scalar-bilinear condensation in a strongly interacting non-abelian gauge sector, which is connected to…

The reheating era leptogenesis in models with seesaw mechanism

Yuta Hamada, Koji Tsumura, Daiki Yasuhara

Observed baryon asymmetry can be achieved not only by the decay of right-handed neutrinos but also by the scattering processes in the reheating era. In the latter scenario, new phy…

Quark mass dependence of H-dibaryon

Yasuhiro Yamaguchi, Tetsuo Hyodo

The H-dibaryon is the exotic multiquark state with baryon number 2 and strangeness . The existence of the deeply bound H-dibaryon is excluded by the observation of the double h…
