Detectable subhalo impacts in Milky Way streams
Junyang Lu, Elias Bernreuther, Tongyan Lin +3
Dark matter subhalos leave gravitational imprints in the stellar streams of the Milky Way. Observing individual strong impacts of subhalos offers a compelling way to constrain and…
Sub-GeV dark matter and multi-decay signatures from dark showers at beam-dump experiments
Elias Bernreuther, Nicoline Hemme, Felix Kahlhoefer +2
In models of strongly-interacting dark sectors, the production of dark quarks at accelerators can give rise to dark showers with multiple dark mesons in the final state. If some of…
Stopping Dark Mesons in Their Tracks with Long-Lived Particle and Resonant Signatures
Pouya Asadi, Austin Batz, Elias Bernreuther +3
Dark sectors with confining gauge interactions can provide both simple dark matter candidates and striking signals at colliders. We recast Large Hadron Collider searches for two di…
Multi-top signals of vectorlike quarks at the LHC
Elias Bernreuther, Bogdan A. Dobrescu
We point out that events with 6 or more top quarks may be observed at the LHC if certain particles exist at the TeV scale. In a model where a vectorlike quark of charge 2/3 decays…
