Alternative Minimal U(1)
Kento Asai, Kazunori Nakayama, Shih-Yen Tseng
We provide a minimal alternative gauged U(1) model in which three right-handed neutrinos with charges of (5,-4,-4) and only one B-L Higgs field with charge 1 are introd…
Search for U(1) charged Dark Matter with neutrino telescope
Kento Asai, Shohei Okawa, Koji Tsumura
We study a simple Dirac fermion dark matter model in U(1) theory. The new light gauge boson plays important roles in both dark matter physics and the explanation fo…
Dark Photon from Light Scalar Boson Decays at FASER
Takeshi Araki, Kento Asai, Hidetoshi Otono +2
FASER is one of the promising experiments which search for long-lived particles beyond the Standard Model. In this paper, we focus on dark photon associating with an additional U(1…
Leptogenesis in the minimal gauged U(1) model and the sign of the cosmological baryon asymmetry
Kento Asai, Koichi Hamaguchi, Natsumi Nagata +1
The minimal gauged U(1) model is a simple extension of the Standard Model and has a strong predictive power for the neutrino sector. In particular, the mass spectrum an…
