EPJ A Highlight - Nuclear physics with a medium-energy Electron-Ion Collider

Possible realizations of a medium-energy EIC: MEIC at Jefferson Lab (top) and eRHIC at Brookhaven National Lab (bottom)

Quarks and gluons are the fundamental constituents of most of the matter in the visible Universe; Quantum Chromodynamics (QCD), a relativistic quantum field theory based on color gauge symmetry, describes their strong interactions. The understanding of the static and dynamical properties of the visible strongly interacting particles - hadrons - in terms of quarks and gluons is one of the most fascinating issues in hadron physics and QCD. In particular the exploration of the internal structure of protons and neutrons is one of the outstanding questions in experimental and theoretical nuclear and hadron physics. Impressive progress has been achieved recently.

The paper, clearly and concisely, addresses several of the issues related to the microscopic structure of hadrons and nuclei: (i) the three–dimensional structure of the nucleon in QCD, which involves the spatial distributions of quark and gluons , their orbital motion, possible correlations between spin and intrinsic motion; (ii) the fundamental color fields in nuclei (nuclear parton densities, shadowing, coherence effects, color transparency); (iii) the conversion of color charge to hadrons (fragmentation, parton propagation through matter, in–medium jets).

The conceptual aspects of these questions are briefly reviewed and the measurements that would address them are discussed, with emphasis on the new information that could be obtained with experiments at an electron-ion collider collider (EIC). Such a medium–energy EIC could be realized at Jefferson Lab after the 12 GeV upgrade (MEIC), or at Brookhaven National Lab as the low–energy stage of eRHIC.

This was our first experience of publishing with EPJ Web of Conferences. We contacted the publisher in the middle of September, just one month prior to the Conference, but everything went through smoothly. We have had published MNPS Proceedings with different publishers in the past, and would like to tell that the EPJ Web of Conferences team was probably the best, very quick, helpful and interactive. Typically, we were getting responses from EPJ Web of Conferences team within less than an hour and have had help at every production stage.
We are very thankful to Solange Guenot, Web of Conferences Publishing Editor, and Isabelle Houlbert, Web of Conferences Production Editor, for their support. These ladies are top-level professionals, who made a great contribution to the success of this issue. We are fully satisfied with the publication of the Conference Proceedings and are looking forward to further cooperation. The publication was very fast, easy and of high quality. My colleagues and I strongly recommend EPJ Web of Conferences to anyone, who is interested in quick high-quality publication of conference proceedings.
