Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

We lay out a comprehensive physics case for a future high-energy muon collider, exploring
a range of collision energies (from 1 to 100 TeV) and luminosities. We highlight the …

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 …

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 …

An overwhelming number of theoretical predictions for hadron colliders require parton
distribution functions (PDFs), which are an important ingredient of theory infrastructure for …

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 …

A bstract With the long-standing tension between experiment and Standard-Model (SM)
prediction in the anomalous magnetic moment of the muon a μ recently reaffirmed by the …

We propose a space-based interferometer surveying the gravitational wave (GW) sky in the
milli-Hz to μ-Hz frequency range. By the 2040s, the μ-Hz frequency band, bracketed in …

Top quarks represent unique high-energy systems since their spin correlations can be
measured, thus allowing to study fundamental aspects of quantum mechanics with qubits at …

Parton showers are among the most widely used tools in collider physics. Despite their key
importance, none so far have been able to demonstrate accuracy beyond a basic level …
