Automatic Peccei-Quinn symmetry
M. B. Gavela, M. Ibe, P. Quilez +1
We present a dynamical (composite) axion model where the Peccei-Quinn (PQ) symmetry arises automatically as a consequence of chirality and gauge symmetry. The Standard Model is sim…
Ultraviolet Completion of a Composite Asymmetric Dark Matter Model with a Dark Photon Portal
Masahiro Ibe, Ayuki Kamada, Shin Kobayashi +2
Composite asymmetric dark matter scenarios naturally explain why the dark matter mass density is comparable with the visible matter mass density. Such scenarios generically require…
Quintessence Axion Revisited in Light of Swampland Conjectures
Masahiro Ibe, Masahito Yamazaki, Tsutomu T. Yanagida
We point out that the swampland conjectures, forbidding the presence of global symmetries and (meta-)stable de Sitter vacua within quantum gravity, pick up a dynamical axion for th…
The swampland conjecture and the Higgs expectation value
Koichi Hamaguchi, Masahiro Ibe, Takeo Moroi
The recently proposed de Sitter swampland conjecture excludes local extrema of a scalar potential with a positive energy density in a low energy effective theory. Under the conject…
as a Gauged Peccei-Quinn Symmetry
Masahiro Ibe, Motoo Suzuki, Tsutomu T. Yanagida
The gauged Peccei-Quinn (PQ) mechanism provides a simple prescription to embed the global PQ symmetry into a gauged symmetry. As it originates from the gauged PQ symmetry, t…
Composite Asymmetric Dark Matter with a Dark Photon Portal
Masahiro Ibe, Ayuki Kamada, Shin Kobayashi +1
Asymmetric dark matter (ADM) is an attractive framework relating the observed baryon asymmetry of the Universe to the dark matter density. A composite particle in a new strong dyna…
