Special Issue Information

Dear Colleagues,

In the standard model of particle physics, baryon number (B) and lepton number (L) represent accidental global symmetries violated only by non-perturbative weak effects, and the combination B - L is exactly conserved. The exact conservation of B and L has been questioned since there is no evidence that they are fundamental. In some theories on physics beyond the standard model, B or (and) L are violated, though constrained by the stability of matter. In fact, the breaking of B and L symmetries would have deep impacts on our understanding of nature, for example, the origin of matter and anti-matter asymmetry and neutrino mass. This Special Issue will include publications on experiments, phenomenology, and theory related to B and L symmetries in particle physics.

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.
