Special Issue Information
Dear Colleagues,
In agreement with the Big Bang theory, the same quantity of matter and anti-matter must be created at the beginning of the universe. In addition, when matter and anti-matter collide, they annihilate producing photons. As a consequence of this primordial annihilation, the Universe is permeated of photons, this phenomenon is known as Cosmic Microwave Background. Up to date, we know that not all the matter and anti-matter annihilated was converted into photons, carrying out the so-called Baryon Asymmetry of the Universe (BAU). On the other hand, according to Sakharov’s conditions, any successful theory of BAU must contain CP-violating processes.
In 1964 the CP violation was first observed in decays of neutral kaons, but not in enough amount to explain the observed BAU, but at least allowed to show that matter and anti-matter are intrinsically different. This CP-violating phenomenon was explained in the context of the Standard Model (SM), including the existence of a third generation of quarks, not seen up to that moment.
As is well known, the Standard Model must be incomplete and extra sources of CP violation must exist to explain BAU after the Big Bang. Therefore, several extensions of the SM have been proposed, and most of them contain additional sources of CP violation. Then, if any of these extensions is correct, the first proof of physics beyond the SM may come from searches of CP violation.
Research articles/review articles on experimental results as well as new phenomenological/theoretical ideas are welcome to be part of this Special Issue.

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. Universe is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. 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.
