Special Issue Information

Dear Colleagues,

The symmetry principle is crucial in the development of theories describing the fundamental interactions between elementary particles. The symmetries of the standard model include both gauge symmetries embedded into the model, as well as accidental symmetries, such as baryon and lepton number conservation. Charge, parity, and the combined charge–parity symmetries are known to be conserved by strong interactions and broken by weak ones. The study of CP violation in the heavy-flavor sector is a main area of research for modern collider experiments. Numerous models of beyond-the-standard-model physics are built based on an idea of symmetry. This Special Issue will cover all aspects of symmetry and asymmetry, including the role of symmetry in models of fundamental interactions. We invite researchers to contribute original and high-quality research papers inspiring advances in hadron and quark physics. Potential topics include, but are not limited to:

  • CP violation in beauty hadrons;
  • CP violation in charm hadrons;
  • CKM matrix;
  • Symmetries and asymmetries in weak interactions;
  • Symmetries and asymmetries in strong interactions;
  • Hadron spectroscopy.

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.

Rare decays of the Higgs boson into a pair of diquarks cc(bb) and c¯c¯(b¯b¯) are studied within the perturbative Standard Model and relativistic quark model. The relativistic corrections determined by the relative motion of quarks are calculated using the production amplitude and the diquark wave functions. Numerical values of the decay widths of the Higgs boson into a baryon pair ccq(bbq) and c¯c¯q¯(b¯b¯q¯) are obtained. Full article

Lepton flavor universality exists in the Standard Model, and hence any observation of the violation of this universality will be a hint for new physics. Recent experimental searches for processes violating this symmetry have attracted much attention among theorists and experimentalists alike. In recent years, such hints have been observed in flavor changing neutral current weak processes such as bsll and charged current weak processes such as bclν processes by collider experiments like Belle, Belle II, BaBar, LHCb, ATLAS, and CMS collaborations, where b,s,c are the bottom, strange, and charm quarks, respectively, and l,ν stand for lepton and the corresponding lepton neutrino, respectively. This article is a review of some of the interesting anomalies observed in the B-sector and includes decays of Bs mesons. Full article
