Current Trends in Neutrino Oscillation Physics: A Phenomenological and Experimental Perspective

Dear Colleagues,

The current landscape of neutrino oscillation physics is very intriguing. On the one hand, the currently running neutrino experiments T2K in Japan and NOnA in the USA are giving us hints about the remaining unknowns in standard oscillation physics, while, on the other hand, there are several upcoming experiments which aim to firmly establish these hints. Examples of such experiments are T2HK, DUNE, ESSnuSB, JUNO, etc. These experiments can also look for new physics scenarios beyond the standard three-flavour model. These experiments can also test various theoretical models which predict certain values of neutrino oscillation parameters. By using the neutrino detectors of these experiments, it is also possible to study oscillations of neutrinos from natural sources: i.e., solar neutrinos, atmospheric neutrinos, supernova neutrinos, etc. One of the new physics scenarios is represented by sterile neutrino oscillations: the short-baseline experiment MicrooBooNE has already given its first results on steriles, and several other experiments like ICARUS, SBND, STEREO, NEOS, JSNS2, etc., are planning to do so in the future. To reduce the systematic uncertainties of neutrino oscillation experiments coming from uncertainty about the neutrino interaction cross-section with matter, dedicated campaigns for cross-section measurement have been proposed by some of the above-mentioned experiments. Additionally, there are dedicated experiments like ENUBET, NINJA and MINERvA which aim to further reduce the uncertainty in the cross-section.

The aim of this Special Issue is to document the current trends and progress in neutrino oscillation physics from a phenomenological and experimental point of view. Therefore, in this Special Issue, we invite original or review articles in all areas of neutrino oscillation physics from the perspectives of phenomenology and experiments.

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.
