This report describes the physics case, the resulting detector requirements, and the evolving
detector concepts for the experimental program at the Electron-Ion Collider (EIC). The EIC …

Lepton scattering is an established ideal tool for studying inner structure of small particles
such as nucleons as well as nuclei. As a future high energy nuclear physics project, an …

There are two mass generating mechanisms in the standard model of particle physics (SM).
One is related to the Higgs boson and fairly well understood. The other is embedded in …

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

Abstract This White Paper aims at highlighting the important benefits in the science reach of
the EIC. High luminosity operation is generally desirable, as it enables producing and …

The last decade has seen a marked shift in how the internal structure of hadrons is
understood. Modern experimental facilities, new theoretical techniques for the continuum …

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 …

Visible matter is characterised by a single mass scale; namely, the proton mass. The
proton's existence and structure are supposed to be described by quantum chromodynamics …

The questions of how the bulk of the Universe's visible mass emerges and how it is manifest
in the existence and properties of hadrons are profound, and probe the heart of strongly …

We present a calculation of the pion valence quark distribution extracted using the formalism
of reduced Ioffe-time pseudodistributions or more commonly known as pseudo-PDFs. Our …
