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 …

We propose in this White Paper a concept for a space experiment using cold atoms to
search for ultra-light dark matter, and to detect gravitational waves in the frequency range …

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 …

Detector and event visualization are essential parts of the software used in high-energy
physics (HEP) experiments. Modern visualization techniques and multimedia production …

The existence of nonzero neutrino masses points to the likely existence of multiple Standard
Model neutral fermions. When such states are heavy enough that they cannot be produced …

We present the automation of one-loop computations in the standard-model effective field
theory at dimension 6. Our general implementation, dubbed smeft@ nlo, covers all types of …

We provide an overview of the status of Monte-Carlo event generators for high-energy
particle physics. Guided by the experimental needs and requirements, we highlight areas of …

Abstract The Large Hadron–Electron Collider (LHeC) is designed to move the field of deep
inelastic scattering (DIS) to the energy and intensity frontier of particle physics. Exploiting …

Rare decays mediated by b→ s ν ν¯ transitions have been reported by the Belle II
experiment. The branching ratio of the decay B+→ K+ ν ν¯ is found to be enhanced with …

In this white paper for the 2021 Snowmass process, we give a description of the proposed
Future Circular Collider (FCC) project and its physics program. The paper summarizes and …
