Special Issue Information

Dear Colleagues,

One of the major issues in modern particle and astroparticle physics is the determination of the nature of dark matter. The existence of an unknown source of matter which affects the gravitational interactions of astrophysical objects at scales of galaxies or larger and which is also implied by the analysis of the spectrum of the cosmic microwave background is a problem that the Standard Model of particle physics does not address in its current state. Dark matter candidates can be detected and studied in different ways, ranging from cosmological observations, direct or indirect detection, or even by producing them at colliders, assuming such particles are within the reach of current or future machines. If experimental observations are made in any of these fields which could be interpreted as originating from a dark matter candidate, the determination of its properties, such as mass, spin and interactions, would not be straightforward, given its elusive nature. On the other hand, the possibility of characterising observations of signatures compatible with the existence of dark matter would point towards possible theoretical models which predict its existence and, possibly, exclude others. The possibility of characterising the properties of dark matter candidates is therefore one of the main goals for current and future searches. Pinpointing the nature of dark matter by combining the potentialities of colliders with results from direct and indirect detection experiments or cosmological observations is the focus of this issue. Attention is given to new and advanced statistical methods for data analysis and to the possibility to use machine learning techniques for the characterisation of new signals.

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.

This is a brief review of aspects of galactic astrophysics and astronomy which have a possible bearing on particle dark matter. It is still quite normal for particle physicists to try to solve “well known anomalies“ that are apparently seen in observations of galaxies (missing satellites, cusp vs. core, etc.) whereas a lot of these anomalies have actually been resolved many years ago. We will try to briefly review the field and discuss many of the areas in question. Full article

Possible dark matter candidates in particle physics span a mass range extending over fifty orders of magnitude. In this review, we consider the range of masses from a few keV to a few hundred TeV, which is relevant for cold particle dark matter. We will consider models where dark matter arises as weakly coupled elementary fields and models where dark matter is a composite state bound by a new strong interaction. Different production mechanisms for dark matter in these models will be described. The landscape of direct and indirect searches for dark matter and some of the resulting constraints on models will be briefly discussed. Full article

Indirect searches for dark matter are based on detecting an anomalous flux of photons, neutrinos or cosmic-rays produced in annihilations or decays of dark matter candidates gravitationally accumulated in heavy cosmological objects, like galaxies, the Sun or the Earth. Additionally, evidence for dark matter that can also be understood as indirect can be obtained from early universe probes, like fluctuations of the cosmic microwave background temperature, the primordial abundance of light elements or the Hydrogen 21-cm line. The techniques needed to detect these different signatures require very different types of detectors: Air shower arrays, gamma- and X-ray telescopes, neutrino telescopes, radio telescopes or particle detectors in balloons or satellites. While many of these detectors were not originally intended to search for dark matter, they have proven to be unique complementary tools for direct search efforts. In this review we summarize the current status of indirect searches for dark matter, mentioning also the challenges and limitations that these techniques encounter. Full article
