Affleck-Dine inflation
James M. Cline, Matteo Puel, Takashi Toma
The Affleck-Dine mechanism in its simplest form provides baryogenesis from the out-of-equilibrium evolution of a complex scalar field with a simple renormalizable potential. We sho…
Relativistic Freeze-in
Oleg Lebedev, Takashi Toma
We study production of scalar dark matter via the freeze--in mechanism in the relativistic regime, focussing on the simplest Higgs portal model. We derive the corresponding relativ…
Real Scalar Dark Matter: Relativistic Treatment
Giorgio Arcadi, Oleg Lebedev, Stefan Pokorski +1
A stable real scalar provides one of the simplest possibilities to account for dark matter. We consider the regime where its coupling to the Standard Model fields is negligibly sma…
Pseudo-Goldstone dark matter confronts cosmic ray and collider anomalies
James M. Cline, Takashi Toma
Persistent excesses in the spectra of gamma rays from the galactic center and cosmic ray antiprotons can be explained by dark matter of mass \,GeV annihilating into …
A --philic scalar doublet under flavor symmetry
Yoshihiko Abe, Takashi Toma, Koji Tsumura
We propose a minimal model which accommodates the long-standing anomaly of muon magnetic moment based on abelian discrete flavor symmetries. The standard model is extended by scala…
