Special Issue Information

Dear Colleagues,

Double-beta decay is one of the current research topics of great interest due its potential to unravel key unknown information on a broad range of issues including violation of conservation laws, fundamental properties of neutrinos, various lepton number violating mechanisms that could contribute to neutrinoless double-beta decay. 

The experimental efforts aim at the deployment of large-scale experiments with large masses of active isotopes that increase the sensitivity, reduce the background contributions and improve the technical performance of the measurements.  The so-called "tonne-phase" searches will attain sensitivities for neutrinoless double beta decay half-lives of the order of 1027-28 years, which would reach the inverted mass hierarchy region for the effective Majorana mass parameter. The discovery of neutrinoless double beta decay, or measurement of any improved limit of its half-life, can be used to constrain the absolute neutrino mass scale and various possible mechanisms that can contribute to this decay mode. Additionally, from an accurate analysis of the emitted electron spectra, signatures of Lorentz invariance violations are searched as well. 

On the theoretical side, there is a continuous effort to provide precise calculations to support the data analysis and interpretation.  The main challenge remains the computation of the nuclear matrix elements whose values still differ too much among different methods, thus affecting the decay rate predictions and the constraint of different lepton violation mechanisms. New methods and techniques are recently developed, from phenomenological approaches to ab initio methods. In addition, experimental studies of single beta decays, muon captures, and charge exchange reactions are used to improve theoretical calculations for the double-beta decay nuclear matrix elements. Additionally, precise calculations of the electron spectra and their angular correlations are used to search for new physics beyond the Standard Model.

In this research topic volume we aim to gather relevant results in the double-beta decay field. Submissions can be recent research and theoretical or experimental reviews.

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.
