Special Issue Information

Dear Colleagues,

In the classical quark model, hadrons are assumed to be composed of three quarks (baryons) or a quark–antiquark pair (mesons). However, as the theoretical basis of strong interaction, quantum chromodynamics (QCD), which is a gauge theory based on the fundamental property of the SU(3) color symmetry, does not rule out multiquark states.

In the last two decades, lots of candidates of the exotic hadrons have been observed. For instance, the charmonium-like state X(3872) and the Pc resonances both show properties that do not fit well with the concept of the traditional hadrons. These observations have triggered intensive investigations on the structure, production, and decay of exotic hadrons. On the other hand, it has been shown that multiquark components in hadrons should play an important role in hadron properties.

The QCD-inspired constituent quark model, which involves symmetries in hadrons, has been successfully applied to hadronic physics. However, it is essential to further develop the quark model in order to describe the current hadronic experiments. Consequently, this Special Issue invites contributions on developments and applications of the constituent quark model, especially on studies of the exotic hadrons and multiquark components in hadrons.

Nevertheless, it remains open also to contributions from other pertinent areas in hadronic physics.

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. 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.

Abstract
A formalism for the experimental analysis of mesons produced by a beam of linearly polarized photons is presented. This formalism introduces a more general use of the reflectivity operator.

A formalism for the experimental analysis of mesons produced by a beam of linearly polarized photons is presented. This formalism introduces a more general use of the reflectivity operator. The goal is to recognize resonances in cross-sections, their associated quantum numbers, and production mechanisms by performing partial wave analysis of multiple-meson final states. Full article
