Bubble Misalignment Mechanism for Axions

Junseok Lee, Kai Murai, Fuminobu Takahashi +1

We study the dynamics of axions at first-order phase transitions in non-Abelian gauge theories. When the duration of the phase transition is short compared to the timescale of the…

Primordial Origin of Supermassive Black Holes from Axion Bubbles

Kentaro Kasai, Masahiro Kawasaki, Naoya Kitajima +3

We study a modification of the primordial black hole (PBH) formation model from axion bubbles. We assume that the Peccei-Quinn scalar rolls down in the radial direction from a larg…

Muon $g - 2$ and non-thermal leptogenesis in $U (1)_{L_{μ} - L_{τ}}$ model

Shintaro Eijima, Masahiro Ibe, Kai Murai

The gauged $U (1)_{L_{μ} - L_{τ}}$ symmetry is the simplest possibility to explain the observed muon $g - 2$ , while being consistent with the neutrino oscillations through the seesaw mechan…
