Understanding the properties of nuclear matter and its emergence through the underlying partonic structure and dynamics of quarks and gluons requires a new experimental facility in hadronic physics known as the Electron-Ion Collider (EIC). The EIC will address some of the most profound questions concerning the emergence of nuclear properties by precisely imaging gluons and quarks inside...
After a brief introduction to the Electron-Ion Collider (EIC) and the Joint ECFA-NuPECC-APPEC Activity on "Synergies between the Electron-Ion Collider and the Large Hadron Collider experiments", I will go into examples of such synergies, focusing mostly on the QCD related ones: parton densities of protons and nuclei, quarkonium production, transverse momentum dependent parton distributions...
One of the fundamental questions in our understanding of the proton structure is the proton spin puzzle. Theoretically, adding all the helicities and orbital angular momenta (OAM) of the quarks and gluons in the proton should give us 1/2, the spin of the proton. At the same time, adding the experimentally measured spin carried by the quarks and gluons in the proton comes up short, presently...
