Inelastic Dirac Dark Matter
Anastasiia Filimonova, Sam Junius, Laura Lopez Honorez +1
Feebly interacting thermal relics are promising dark matter candidates. Among them, scenarios of inelastic Dark Matter evade direct detection by suppressed elastic scattering off a…
Displaced or invisible? ALPs from decays at Belle II
Torben Ferber, Anastasiia Filimonova, Ruth Schäfer +1
At colliders, neutral long-lived particles can be detected through displaced decay products or as missing energy. Which search strategy is better depends on the particle's decay le…
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…
Physics reach of a long-lived particle detector at Belle II
Sascha Dreyer, Torben Ferber, Anastasiia Filimonova +9
We have studied three realistic benchmark geometries for a new far detector GAZELLE to search for long-lived particles at the \superkekb accelerator in Tsukuba, Japan. The new dete…
Soft displaced leptons at the LHC
Freya Blekman, Nishita Desai, Anastasiia Filimonova +2
Soft displaced leptons are representative collider signatures of compressed dark sectors with feeble couplings to the standard model. Prime targets are dark matter scenarios where…
An Extended Analysis of Heavy Neutral Leptons during Big Bang Nucleosynthesis
Nashwan Sabti, Andrii Magalich, Anastasiia Filimonova
Heavy Neutral Leptons (HNLs) are strongly motivated by theory due to their capability of simultaneously explaining the observed phenomena of dark matter, neutrino oscillations and…
Probing dark sectors with long-lived particles at BELLE II
Anastasiia Filimonova, Ruth Schäfer, Susanne Westhoff
We propose a new search for light scalar singlets in rare meson decays. For tiny interactions, the scalar is long-lived at detector scales and decays into displaced pairs of lepton…
Long live the Higgs portal!
Anastasiia Filimonova, Susanne Westhoff
In Higgs portal models of fermion dark matter, scalar couplings are unavoidably suppressed by strong bounds from direct detection experiments. As a consequence, thermal dark matter…
