A golden age for heavy-quarkonium physics dawned a decade ago, initiated by the
confluence of exciting advances in quantum chromodynamics (QCD) and an explosion of …

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

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 …

Ultra-peripheral collisions (UPCs) have been a significant source of study at RHIC and the
LHC. In these collisions, the two colliding nuclei interact electromagnetically, via two-photon …

The ALICE Collaboration at the LHC has measured the J/ψ and ψ′ photoproduction at mid-
rapidity in ultra-peripheral Pb–Pb collisions at\(\sqrt {s_ {\mathrm {NN}}}= 2.76~\mathrm …

The ALICE Collaboration has made the first measurement at the LHC of J/ψ photoproduction
in ultra-peripheral Pb–Pb collisions at sNN= 2.76 TeV. The J/ψ is identified via its dimuon …

Prospects for quarkonium-production studies accessible during the upcoming high-
luminosity phases of the CERN Large Hadron Collider operation after 2021 are reviewed …

The cross section for coherent J/ψ photoproduction accompanied by at least one neutron on
one side of the interaction point and no neutron activity on the other side, X n 0 n, is …

Exclusive dimuon production in ultraperipheral collisions (UPC), resulting from photon-
photon interactions in the strong electromagnetic fields of colliding high-energy lead nuclei …

Abstract Proton–nucleus (p+ A) collisions have long been recognized as a crucial
component of the physics program with nuclear beams at high energies, in particular for …
