Special Issue Information

Dear Colleagues,

What we call Dark Matter still remains unknown. In the surge of experimental challenges to detect Dark Matter and theoretical attempts to conjecture its nature, new efforts exploring alternative mechanisms of Dark Matter and other hidden sector effects should not be neglected. In this issue of Symmetry, we should bring together experimental and theoretical ideas that focus on neutrons as a possible messenger of Dark Matter physics. More than four σ difference in neutron lifetime measured by appearance and disappearance methods and other anomalies seen in the disappearance of ultra-cold neutrons indicate that neutrons can decay or oscillate into a hidden sector. Oscillations of neutral particles of the Standard Model, including but not limited to photons, neutrinos, and neutrons, have been discussed in the literature. However, a large lifetime of the neutron and its strong interaction, together with availability of cold and ultra-cold neutron sources, are making this particle unique for a variety of simple experiments. Thus, for example, a theoretically viable model of Dark Matter comprising the symmetric or asymmetric Mirror Matter, where the mirror neutron is a twin neutral baryon of the mirror world, can be tested experimentally appearing as various interesting quantum mechanical effects. Mirror neutrons can also modify the properties of neutron stars.

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 papers will be 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 1800 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.
