Abstract The standard Λ Cold Dark Matter (ΛCDM) cosmological model provides a good
description of a wide range of astrophysical and cosmological data. However, there are a …

Particle physics today faces the challenge of explaining the mystery of dark matter, the origin
of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent …

Abstract The Forward Physics Facility (FPF) is a proposal to create a cavern with the space
and infrastructure to support a suite of far-forward experiments at the Large Hadron Collider …

We report the first direct observation of neutrino interactions at a particle collider experiment.
Neutrino candidate events are identified in a 13.6 TeV center-of-mass energy pp collision …

The present white paper is submitted as part of the “Snowmass” process to help inform the
long-term plans of the United States Department of Energy and the National Science …

The theory of the strong force, quantum chromodynamics, describes the proton in terms of
quarks and gluons. The proton is a state of two up quarks and one down quark bound by …

Astrophysical neutrinos are excellent probes of astroparticle physics and high-energy
physics. With energies far beyond solar, supernovae, atmospheric, and accelerator …

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

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 This White Paper presents an overview of the current status and future perspective
of QCD research, based on the community inputs and scientific conclusions from the 2022 …
