Special Issue Information
Dear Colleagues,
Symmetries play a key role in modern physics. Conceptually, they provide organizing principles for building models. Pragmatically, they provide selection rules which simplify many computations. Phenomenologically, symmetries provide rationales for hierarchy problems and novel discoveries. To wit, the framework of (spontaneous) symmetry breaking drives many features of effective field theories and collective phenomena, and the structure of the Higgs mechanism in the standard model has led to correct predictions decades in advance.
A natural step in this direction is the inception of supersymmetry and its gravitational counterpart, supergravity. In addition to completing the structure of weakly coupled relativistic quantum fields with the gravitino, supersymmetry quickly found a spotlight in model building for particle physics beyond the standard model due to its attractive implications for electroweak hierarchy and dark matter problems.
String theory is a natural home for all these ideas, able to incorporate gravity, gauge interactions, and supersymmetry in a coherent quantum–mechanical framework. It is thus paramount to narrow down which kind of gauge groups, representations, and supercharges can survive its formidable consistency constraints.
In this Special Issue, we would like to explore how symmetries and their breaking or gauging arise in string theory and whether general lessons can be drawn from them.

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. 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.
