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…
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…
Angular Resolution of Electrons in Gaseous Targets
Majd Ghrear, Sven E. Vahsen
Low-energy electron recoils are of interest in several planned and proposed future nuclear and particle physics experiments. The topology and directions of such recoils provide imp…
A Comparison of Micromegas with x/y Strip Charge Readouts for Directional Recoil Detection
Majd Ghrear, Alasdair G. McLean, Hima B. Korandla +3
Detecting the topology and direction of low-energy nuclear and electronic recoils is broadly desirable in nuclear and particle physics, with applications in coherent elastic neutri…
CYGS: Detecting solar neutrinos with directional gas time projection chambers
Chiara Lisotti, Ciaran A. J. O'Hare, Elisabetta Baracchini +8
CYGNUS is a proposed global network of large-scale gas time projection chambers (TPCs) with the capability of directionally detecting nuclear and electron recoils at keV e…
Deep Probabilistic Direction Prediction in 3D with Applications to Directional Dark Matter Detectors
Majd Ghrear, Peter Sadowski, Sven Einar Vahsen
We present the first method to probabilistically predict 3D direction in a deep neural network model. The probabilistic predictions are modeled as a heteroscedastic von Mises-Fishe…
Deep learning for improved keV-scale recoil identification in high resolution gas time projection chambers
J. Schueler, M. Ghrear, S. E. Vahsen +2
Recoil-imaging gaseous time projection chambers (TPCs) with directional sensitivity are attractive for dark matter (DM) searches. Detectors capable of reconstructing 3D nuclear rec…
Recoil imaging for directional detection of dark matter, neutrinos, and physics beyond the Standard Model
C. A. J. O'Hare, D. Loomba, K. Altenmüller +164
Recoil imaging entails the detection of spatially resolved ionization tracks generated by particle interactions. This is a highly sought-after capability in many classes of detecto…
Observables for Recoil Identification in High-Definition Gas Time Projection Chambers
Majd Ghrear, Sven E. Vahsen, Cosmin Deaconu
Directional detection of nuclear recoils is broadly desirable in nuclear and particle physics. At low recoil energies, this capability may be used to confirm the cosmological origi…
CYGNUS: Feasibility of a nuclear recoil observatory with directional sensitivity to dark matter and neutrinos
S. E. Vahsen, C. A. J. O'Hare, W. A. Lynch +16
Now that conventional weakly interacting massive particle (WIMP) dark matter searches are approaching the neutrino floor, there has been a resurgence of interest in detectors with…
Edge Modes and Teleportation in a Topologically Insulating Quantum Wire
Majd Ghrear, Brie Mackovic, Gordon W. Semenoff
We find a simple model of an insulating state of a quantum wire which has a single isolated edge mode. We argue that, when brought to proximity, the edge modes on independent wires…
