Light Dark Matter Discovery Potential and Model Selection at LDMX
Adam Berger, Riccardo Catena, Jan Conrad +1
Light dark matter (DM) is a compelling scenario for the observed relic abundance, with accelerator-based searches as a powerful discovery strategy. The upcoming Light Dark Matter e…
Light Vector Dark Matter via a Magnetic Dipole Portal: Bridging Direct Detection and Fixed-Target Searches
Avik Banerjee, Riccardo Catena, Taylor R. Gray
We present a model featuring sub-GeV vector dark matter by augmenting the Standard Model with a new non-Abelian dark , spontaneously broken by the vacuum expectation value…
LDMX -- The Light Dark Matter eXperiment
Torsten Akesson, Layan Alsaraya, Stephen Appert +116
The Light Dark Matter eXperiment (LDMX) is an electron fixed-target experiment optimized to search for sub-GeV dark matter production through the missing momentum signature. LDMX i…
Production of Dark Photons through Higher Electromagnetic Moments at LDMX: Simulations and Model Discrimination
Riccardo Catena, Taylor R. Gray, Thomas Jerkvall
We extend the projected sensitivity of LDMX for sub-GeV dark matter (DM) to the case of dark photons produced through higher order electromagnetic moments. These moments arise from…
On the dark matter origin of an LDMX signal
Riccardo Catena, Taylor R. Gray, Andreas Lund
Fixed target experiments where beam electrons are focused upon a thin target have shown great potential for probing new physics, including the sub-GeV dark matter (DM) paradigm. Ho…
Resonant or asymmetric: The status of sub-GeV dark matter
Sowmiya Balan, Csaba Balázs, Torsten Bringmann +9
Sub-GeV dark matter (DM) particles produced via thermal freeze-out evade many of the strong constraints on heavier DM candidates but at the same time face a multitude of new constr…
