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…

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…

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…

Dark matter relic density in strongly interacting dark sectors with light vector mesons

Elias Bernreuther, Nicoline Hemme, Felix Kahlhoefer +1

Stable dark matter particles may arise as pseudo-Goldstone bosons from the confinement of dark quarks interacting via a non-Abelian gauge force. Their relic abundance is determined…

Extracting Halo Independent Information from Dark Matter Electron Scattering Data

Elias Bernreuther, Patrick J. Fox, Benjamin Lillard +2

Direct detection experiments and the interpretation of their results are sensitive to the velocity structure of the dark matter in our galactic halo. In this work, we extend the fo…

Vectorlike leptons and long-lived bosons at the LHC

Elias Bernreuther, Bogdan A. Dobrescu

We study a renormalizable theory that includes a heavy weak-singlet vectorlike lepton, , that decays into a pseudoscalar boson and a tau lepton. We show that this can be…

Searching for dark radiation at the LHC

Elias Bernreuther, Felix Kahlhoefer, Michele Lucente +1

In this work we explore the intriguing connections between searches for long-lived particles (LLPs) at the LHC and early universe cosmology. We study the non-thermal production of…

Theory, phenomenology, and experimental avenues for dark showers: a Snowmass 2021 report

Guillaume Albouy, Jared Barron, Hugues Beauchesne +51

In this work, we consider the case of a strongly coupled dark/hidden sector, which extends the Standard Model (SM) by adding an additional non-Abelian gauge group. These extensions…

Forecasting dark showers at Belle II

Elias Bernreuther, Kai Böse, Torben Ferber +4

Dark showers from strongly interacting dark sectors that confine at the GeV scale can give rise to novel signatures at colliders. In this work, we study the sensitivity of…

On the challenges of searching for GeV-scale long-lived particles at the LHC

Elias Bernreuther, Juliana Carrasco Mejia, Felix Kahlhoefer +2

Many models of dark matter predict long-lived particles (LLPs) that can give rise to striking signatures at the LHC. Existing searches for displaced vertices are however tailored t…

Resonant Sub-GeV Dirac Dark Matter

Elias Bernreuther, Saniya Heeba, Felix Kahlhoefer

We study the phenomenology and detection prospects of a sub-GeV Dirac dark matter candidate with resonantly enhanced annihilations via a dark photon mediator. The model evades cosm…

Casting a graph net to catch dark showers

Elias Bernreuther, Thorben Finke, Felix Kahlhoefer +2

Strongly interacting dark sectors predict novel LHC signatures such as semi-visible jets resulting from dark showers that contain both stable and unstable dark mesons. Distinguishi…

Strongly interacting dark sectors in the early Universe and at the LHC through a simplified portal

Elias Bernreuther, Felix Kahlhoefer, Michael Krämer +1

We study the cosmology and LHC phenomenology of a consistent strongly interacting dark sector coupled to Standard Model particles through a generic vector mediator. We lay out the…

Actual Physics behind Mono-X

Elias Bernreuther, Jan Horak, Tilman Plehn +1

Mono-X searches are standard dark matter search strategies at the LHC. First, we show how in the case of initial state radiation they essentially collapse to mono-jet searches. Sec…

Superadiabatic forces in the dynamics of the one-dimensional Gaussian core model

Elias Bernreuther, Matthias Schmidt

Using Brownian dynamics computer simulations we investigate the dynamics of the one-body density and one-body current in a one-dimensional system of particles that interact with a…
