Probing a light dark sector at future lepton colliders via invisible decays of the SM-like and dark Higgs bosons
Gholamhossein Haghighat, Mojtaba Mohammadi Najafabadi, Kodai Sakurai +1
A renormalizable UV model for Axion-Like Particles (ALPs) or hidden photons, that may explain the dark matter usually involves a dark Higgs field which is a singlet under the stand…
Radiative corrections to decay branching ratios of the CP-odd Higgs boson in two Higgs doublet models
Masashi Aiko, Shinya Kanemura, Kodai Sakurai
We calculate radiative corrections to decay rates of CP-odd Higgs boson for various decay modes in the four types of two Higgs doublet models with the softly broken discrete $Z…
Singlet extensions and W boson mass in the light of the CDF II result
Kodai Sakurai, Fuminobu Takahashi, Wen Yin
Recently, the CDF collaboration has reported the precise measurement of the W boson mass, MeV, based on fb of TeV c…
Suppression of Higgs Mixing by Quantum Zeno Effect
Kodai Sakurai, Wen Yin
The Higgs portal interaction to a singlet sector of the standard model (SM) gauge group is widely-studied. In this Letter, we show that a quantum effect is important if the Higgs f…
Anomaly-free axion dark matter in three Higgs doublet model and its phenomenological implications
Kodai Sakurai, Fuminobu Takahashi
We study phenomenological implications of an axion that arises as a pseudo Nambu-Goldstone boson due to the spontaneous breaking of anomaly-free global flavor symmetry. One interes…
The International Linear Collider: Report to Snowmass 2021
Alexander Aryshev, Ties Behnke, Mikael Berggren +508
The International Linear Collider (ILC) is on the table now as a new global energy-frontier accelerator laboratory taking data in the 2030s. The ILC addresses key questions for our…
