We summarize the ongoing scientific program of the 12 GeV Continuous Electron Beam
Accelerator Facility (CEBAF) and give an outlook into future opportunities. The program …

Abstract Neutrinos are the Standard Model (SM) particles which we understand the least,
often due to how weakly they interact with the other SM particles. Beyond this, very little is …

High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large
number of particles along the beam collision axis, outside of the acceptance of existing LHC …

A bstract Searches for dark photons provide serendipitous discovery potential for other types
of vector particles. We develop a framework for recasting dark photon searches to obtain …

A bstract Light pseudoscalars interacting pre-dominantly with Standard Model gauge
bosons (so-called axion-like particles or ALPs) occur frequently in extensions of the …

The proposed LDMX experiment would provide roughly a meter-long region of instrumented
tracking and calorimetry that acts as a beam stop for multi-GeV electrons in which each …

The recent Belle II observation of B→ KE miss challenges theoretical interpretations in terms
of Standard Model neutrino final states. Instead, we consider new physics scenarios where …

A search for sub-GeV dark matter produced from collisions of the Fermilab 8 GeV Booster
protons with a steel beam dump was performed by the MiniBooNE-DM Collaboration using …

A bstract New light particles produced in supernovae can lead to additional energy loss and
a consequent deficit in neutrino production in conflict with the neutrinos observed from …

Vector bosons heavier than 10-22 eV can be viable dark matter candidates with distinctive
experimental signatures. Ultralight dark matter generally requires a nonthermal origin to …
