Expected Sensitivity of the Light Dark Matter eXperiment to Long-Lived Dark Photons and Axion-Like Particles
Torsten Akesson, Clay Barton, Charles Bell +53
The Light Dark Matter eXperiment (LDMX) is an electron-beam fixed-target experiment primarily designed to achieve world-leading, model-independent sensitivity to sub-GeV dark matte…
First look at continuous spin gravity: Time delay signatures
Shayarneel Kundu, Philip Schuster, Natalia Toro
We consider the possibility that gravity is mediated by "continuous spin" particles, i.e.~ massless particles whose invariant spin scale is non-zero. In this case, the prima…
Cornering MeV-GeV Axions and Dark Photons with LDMX
Sarah Gaiser, Alessandro Russo, Philip Schuster
Axion-like particles (ALPs), the QCD axion, and dark photons in the MeV-GeV mass range are motivated by various dark matter models and the strong CP problem, and are ubiquitous in…
A Prototype Hybrid Mode Cavity for Heterodyne Axion Detection
Zenghai Li, Kevin Zhou, Marco Oriunno +7
In the heterodyne approach to axion detection, axion dark matter induces transitions between two modes of a microwave cavity, resulting in a parametrically enhanced signal power. W…
Sensitivity of an Early Dark Matter Search using the Electromagnetic Calorimeter as a Target for the Light Dark Matter eXperiment
LDMX Collaboration, Torsten à kesson, Elizabeth Berzin +53
The Light Dark Matter eXperiment (LDMX) is proposed to employ a thin tungsten target and a multi-GeV electron beam to carry out a missing momentum search for the production of dark…
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…
