Chiral Quark Models and Their Applications

Dear Colleagues,

This Special Issue, entitled “Chiral Quark Models and Their Applications”, is devoted to recent advances in effective approaches to low-energy Quantum Chromodynamics (QCD), with a particular focus on chiral symmetry and its role in the dynamics of strongly interacting matter. A variety of effective models—including the Nambu–Jona-Lasinio (NJL) model and its extensions, linear and nonlinear sigma models, quark–meson models, and Dyson–Schwinger approaches, among others—have proven essential for understanding spontaneous chiral symmetry breaking, meson properties, and the rich structure of the QCD phase diagram.

We invite contributions that address theoretical developments, phenomenological applications, and comparisons with results from lattice QCD and experimental data. Topics of interest include, but are not limited to, the following: chiral symmetry breaking and restoration, hadron properties, QCD thermodynamics at finite temperature and density, phase transitions and critical phenomena, color superconductivity, the effects of external magnetic fields, and isospin–asymmetric matter.

By providing insight into a broad spectrum of effective models and techniques, this Special Issue aims to highlight their relevance and impact in tackling fundamental questions in the physics of strong interactions and the behavior of hadronic and quark matter under extreme conditions.

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 250 words) can be sent to the Editorial Office for assessment.

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. Symmetry is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). 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.
