Special Issue Information
Dear Colleagues,
The exploration of the structure of the nucleons and nuclei is essential for all aspects of the physics programs of the current/future electron-hadron and electron-ion colliders, based on using medium- and high-energy electron and proton/ion beams, providing ultimate tools for high-precision studies in Quantum Chromodynamics. Such colliders are the US Electron-Ion Collider (EIC) currently under construction at BNL, the proposed CERN’s Large Hadron electron Collider (LHeC) and Electron-Ion Collider in China (EicC), as well as the Future Circular lepton-hadron Collider (FCC-eh), plus the current 12 GeV CEBAF and its potential energy upgrade at Jlab. All these machines are supposed to be excellent laboratories for carrying out studies in many branches of modern nuclear physics, including hadron spectroscopy. The prospective experimental measurements along with theoretical and phenomenological research in hadron spectroscopy will have a major impact, particularly, on our more comprehensive and thorough understanding of non-conventional (exotic) and conventional states that are studied for already several decades in electron-positron annihilation experiments worldwide.
Currently, there are various topics relevant to the spectroscopy programs, which could be of great importance for this Special Issue, including but not limited to
(i) Heavy quarkonium production theory, (ii) XYZ production theory, (iii) XYZ structure and theoretical interpretation, (iv) partial-wave analysis, (v) hadron spectroscopy with lattice QCD.
Some more specific examples are
- Studies of photo- and electroproduction in exclusive, semi-inclusive and inclusive processes that can produce XYZ, multiquark, and baryon-antibaryon molecular states, as well as charm/bottom meson and charmonium/bottomonium states.
- Development of a systematic approach to scattering theory for production and decay of heavy-quark resonances; further development of the mechanisms/models for exotic states’ production.
- Studies of exclusive hadron production and hadronization through heavy-flavor production.
- Studies for conventional and exotic hadrons; calculations of scattering amplitudes in certain channels, where exotic candidates may potentially be observable.
Thereby, our goal is to take a “snapshot” of the present developments, by assembling novel research articles and comprehensive reviews related to the above-mentioned and various other spectroscopy-related potential topics for the current/future electron-hadron and electron-ion colliders. We cordially invite contributions of theoretical and phenomenological nature (including physics simulations as well) from our colleagues working in this broad field of research of modern nuclear physics.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Universe is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
