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 …

Abstract Quark–Gluon Plasma (QGP), a QCD state of matter created in ultra-relativistic
heavy-ion collisions, has remarkable properties including, for example, a low shear viscosity …

1 Executive summary The purpose of this document is to outline the developing scientific
case for pursuing an energy upgrade to 22 GeV of the Continuous Electron Beam …

We review key measurements performed by CMS in the context of its heavy ion physics
program, using event samples collected in 2010–2018 with several collision systems and …

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 …

We show that ultraperipheral heavy-ion collisions at the Large Hadron Collider (LHC) can
be used to search for axionlike particles with mass below 100 GeV. The Z 4 enhanced …

Ultraperipheral collisions (UPCs) of heavy ions and protons are the energy frontier for
electromagnetic interactions. Both photonuclear and two-photon collisions are studied at …

A bstract Exclusive production of transversely polarized heavy vector mesons in deep
inelastic scattering at high energy is calculated at next-to-leading order accuracy in the …

We study the relevance of experimental data on heavy-flavor [D 0, J/ψ, B→ J/ψ and ϒ (1 S)
mesons] production in proton-lead collisions at the LHC to improve our knowledge of the …

The ultrarelativistic heavy-ion programs at the Relativistic Heavy Ion Collider and the Large
Hadron Collider have entered an era of quantitative analysis of quantum chromodynamics …
