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…
Indirect searches for dark matter bound state formation and level transitions
Iason Baldes, Francesca Calore, Kalliopi Petraki +2
Indirect searches for dark matter (DM) have conventionally been applied to the products of DM annihilation or decay. If DM couples to light force carriers, however, it can be captu…
Stochastic Baryogenesis
Yi-Peng Wu, Kalliopi Petraki
Using a multi-field stochastic approach, we investigate the vacuum expectation value (VEV) during inflation of a scalar field charged under a mildly broken global symmetry t…
