Wash-In Leptogenesis
Valerie Domcke, Kohei Kamada, Kyohei Mukaida +2
We present a leptogenesis mechanism based on the standard type-I seesaw model that successfully operates at right-handed-neutrino masses as low as a few 100 TeV. This mechanism, wh…
NANOGrav results and LIGO-Virgo primordial black holes in axion-like curvaton model
Keisuke Inomata, Masahiro Kawasaki, Kyohei Mukaida +1
We discuss a possible connection between the recent NANOGrav results and the primordial black holes (PBHs) for the LIGO-Virgo events. In particular, we focus on the axion-like curv…
Renormalization Group Equations of Higgs- Inflation
Yohei Ema, Kyohei Mukaida, Jorinde van de Vis
We derive one- and two-loop renormalization group equations (RGEs) of Higgs- inflation. This model has a non-minimal coupling between the Higgs and the Ricci scalar and a Ricc…
Spontaneous Baryogenesis from Axions with Generic Couplings
Valerie Domcke, Yohei Ema, Kyohei Mukaida +1
Axion-like particles can source the baryon asymmetry of our Universe through spontaneous baryogenesis. Here we clarify that this is a generic outcome for essentially any coupling o…
Gravitational Wave Production right after a Primordial Black Hole Evaporation
Keisuke Inomata, Masahiro Kawasaki, Kyohei Mukaida +2
We discuss the footprint of evaporation of primordial black holes (PBHs) on stochastic gravitational waves (GWs) induced by scalar perturbations. We consider the case where PBHs on…
Dark Matter bound-state formation at higher order: a non-equilibrium quantum field theory approach
Tobias Binder, Burkhard Blobel, Julia Harz +1
The formation of meta-stable dark matter bound states in coannihilating scenarios could efficiently occur through the scattering with a variety of Standard Model bath particles, wh…
