Saha equilibrium for metastable bound states and dark matter freeze-out
Tobias Binder, Anastasiia Filimonova, Kalliopi Petraki +1
The formation and decay of metastable bound states can significantly decrease the thermal-relic dark matter density, particularly for dark matter masses around and above the TeV sc…
Baryogenesis from ultra-slow-roll inflation
Yi-Peng Wu, Elena Pinetti, Kalliopi Petraki +1
The ultra-slow-roll (USR) inflation represents a class of single-field models with sharp deceleration of the rolling dynamics on small scales, leading to a significantly enhanced p…
Bound states of WIMP dark matter in Higgs-portal models. Part II. Thermal decoupling
Ruben Oncala, Kalliopi Petraki
The Higgs doublet can mediate a long-range interaction between multi-TeV particles coupled to the Weak interactions of the Standard Model, while its emission can lead to very rapid…
Bound states of WIMP dark matter in Higgs-portal models. Part I. Cross-sections and transition rates
Ruben Oncala, Kalliopi Petraki
We investigate the role of the Higgs \emph{doublet} in the thermal decoupling of multi-TeV dark matter coupled to the Weak interactions of the Standard Model and the Higgs. The Hig…
