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 …

The physics of the gravitational form factors of the proton, as well as their understanding
within quantum chromodynamics, has advanced significantly in the past two decades …

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 …

A bstract We review and examine in detail recent developments regarding the question of
the nucleon mass decomposition. We discuss in particular the virial theorem in quantum …

Different decompositions (sum rules) for the proton mass have been proposed in the
literature. All of them are related to the energy-momentum tensor in quantum …

In this work, we find the light front densities for momentum and forces, including pressure
and shear forces, within hadrons. This is achieved by deriving relativistically correct …

The physics case for quarkonium-production studies accessible at the US Electron Ion
Collider is described.

We solve for the gluon generalized parton distributions (GPDs) inside the proton at zero
skewness, focusing specifically on leading twist chiral-even GPDs. We obtain and employ …

We formulate a light-front spectator model for the proton incorporating the gluonic degree of
freedom. In this model, at high energy scattering of the proton, the active parton is a gluon …
