Special Issue Information

Dear Colleagues,

Neutrino oscillations represent the first unambiguous evidence for physics beyond the Standard Model, revealing that neutrinos have mass. This discovery continues to drive diverse experimental and theoretical research.

We invite contributions that span the full scope of this field. Topics of interest include precision measurements of oscillation parameters (θ₁₂, θ₂₃, Δm²₂₁, Δm²₃₁), the ongoing quest to resolve neutrino mass ordering and constrain the CP-violating phase, advances in the theory of neutrino interactions and electron scattering, and investigations of sterile neutrinos, non-standard interactions (NSIs), and other new physics.

We welcome submissions from all experimental frontiers, including accelerator, reactor, atmospheric, and solar, as well as theoretical studies on lepton interactions, the mechanisms of neutrino mass generation, the origin of mixing patterns, and the interplay between these findings and cosmological observations.

Our goal is to capture the current state of the art and progress being made in neutrino physics while illuminating a path toward the field's exciting future.

We look forward to receiving your contributions.

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. 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.

Benefits of Publishing in a Special Issue

Electroweak, QCD, and QED radiative corrections to the nucleon low-energy coupling constants

Electroweak, QCD, and QED radiative corrections to the nucleon low-energy coupling constants

g_{V}

and

g_{A}

are enhanced by large perturbative logarithms between the electroweak and hadronic scale, as well as between the hadronic scale and the low-energy MeV scale. Additionally, higher-order pion-mass splitting corrections to the nucleon axial-vector charge might be large. By consistently incorporating these effects, we provide an updated relation between the lattice-QCD and physical

(

g_{A}^{QCD} = 1.265 (26)

(

g_{A}^{QCD} = 1.240 (9)

) when based on a combination of lattice-QCD and data-driven (or only data-driven) inputs, respectively. Future phenomenological, chiral perturbation theory, and lattice-QCD studies can improve both the central value and the uncertainty of this estimate. Full article

Probing Signatures of Sterile Neutrinos in the MOMENT and DUNE Experiments

Abstract

Motivated by the persistent short-baseline anomalies that hint at the possible existence of physics beyond the standard three-flavor paradigm, we study the phenomenology of light sterile neutrinos in the minimal (3 + 1) framework using two future experiments: the MuOn-decay MEdium-baseline NeuTrino beam experiment (MOMENT) and the Deep Underground Neutrino Experiment (DUNE). We place constraints on active–sterile mixing parameters, probe CP-violation discovery potential, and examine correlations between the standard Dirac CP phase and the additional CP phases arising from active–sterile mixing to quantify phase degeneracies. We present exclusion limits and demonstrate the crucial role of the near detector in improving sensitivities by one or two orders of magnitude compared to a configuration with only the far detector. We find that the presence of sterile neutrinos can reduce the CP-violation sensitivity in long-baseline neutrino oscillation experiments. For large sterile mass splittings, the rapid oscillations average out, leading to strong parameter degeneracies in DUNE. In contrast, MOMENT retains strong sensitivity to CP violation and efficiently disentangles the standard and sterile CP phases. Our results highlight the strong complementarity between DUNE and MOMENT and show that their combined capabilities provide a powerful test of the light sterile neutrino hypothesis in regions of the parameter space that remain weakly constrained by current data.
