Current Status of Top-Specific Variant Axion Model
Cheng-Wei Chiang, Hajime Fukuda, Michihisa Takeuchi +1
The invisible variant axion model is very attractive as it is free from the domain wall problem. This model requires at least two Higgs doublets at the electroweak scale, with one…
Higgsino Dark Matter or Not: Role of Disappearing Track Searches at the LHC and Future Colliders
Hajime Fukuda, Natsumi Nagata, Hidetoshi Otono +1
Higgsino in supersymmetric standard models is known to be a promising candidate for dark matter in the Universe. Its phenomenological property is strongly affected by the gaugino f…
A "Gauged" Peccei-Quinn Symmetry
Hajime Fukuda, Masahiro Ibe, Motoo Suzuki +1
The Peccei-Quinn (PQ) solution to the strong problem requires an anomalous global symmetry, the PQ symmetry. The origin of such a convenient global symmetry is quite pu…
Dark Matter Candidates in a Visible Heavy QCD Axion Model
Hajime Fukuda, Masahiro Ibe, Tsutomu T. Yanagida
In this paper, we discuss dark matter candidates in a visible heavy QCD axion model. There, a mirror copied sector of the Standard Model with mass scales larger than the Standard M…
