Non-thermal Production of PNGB Dark Matter and Inflation
Yoshihiko Abe, Takashi Toma, Koichi Yoshioka
A pseudo Nambu-Goldstone boson (pNGB) is a natural candidate of dark matter in that it avoids the severe direct detection bounds. We show in this paper that the pNGB has another di…
Electroweak axion string and superconductivity
Yoshihiko Abe, Yu Hamada, Koichi Yoshioka
We study the axion strings with the electroweak gauge flux in the DFSZ axion model and show that these strings, called the electroweak axion strings, can exhibit superconductivity…
Implications of the weak gravity conjecture in anomalous quiver gauge theories
Yoshihiko Abe, Tetsutaro Higaki, Rei Takahashi
We argue a smallness of gauge couplings in abelian quiver gauge theories, taking the anomaly cancellation condition into account. In theories of our interest there exist chiral fer…
TeV-scale Majorogenesis
Yoshihiko Abe, Yu Hamada, Takahiro Ohata +2
The Majoron, the Nambu-Goldstone boson of lepton number symmetry, is an interesting candidate for dark matter as it deeply connects the dark matter and neutrino physics. In this pa…
Pseudo-Nambu-Goldstone dark matter from gauged symmetry
Yoshihiko Abe, Takashi Toma, Koji Tsumura
A pseudo-Nambu-Goldstone boson (pNGB) is an attractive candidate for dark matter since the current severe limits of dark matter direct detection experiments are naturally evaded by…
