Symmetries and Anomalies in Flavour Physics

Dear Colleagues,

Flavour physics symmetries provide powerful tools to access new physics beyond the Standard Model. During the past decade, some measurements of B mesons decays have challenged lepton flavour universality (an accidental symmetry of the Standard Model), attracting significant attention as a result. A consistent pattern of anomalies seemed to emerge in neutral–current interactions, which could be explained in models with lepto-quarks or new neutral gauge-bosons. In addition, in charge–current interactions, semileptonic B decays involving τ leptons in the final state favoured larger rates than those that assume lepton flavour universality.

The field has seen quite a dramatic turn recently. New experimental results have been published that are in surprisingly good agreement with the Standard Model, supporting lepton flavour universality. However, tensions continue to exist, which have profound implications for model building and for the discovery potential of current and future experiments.

This Special Issue aims to provide an updated picture of the flavour landscape. We are seeking contributions on the status of flavour anomalies, from an experimental and a theoretical point of view.

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 250 words) can be sent to the Editorial Office for assessment.

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.
