Neutrino masses and solar neutrinos [PDF]
It has been pointed out by Bahcall and Bethe and others that all solar-neutrino data can be explained by Mikheyev-Smirnov-Wolfenstein oscillations with $m({\ensuremath{\nu}}_{\ensuremath{\mu}})\ensuremath{\sim}{10}^{\ensuremath{-}3}$ eV consistent with ideas of grand unified theories (GUT's).

In the last decades, a very important breakthrough has been brought about in the elementary particle physics by the discovery of the phenomenon of the neutrino oscillations, which has shown neutrino properties beyond the Standard Model. But a full understanding of the various aspects of the neutrino oscillations is far to be achieved. In this paper the

Neutrinos in a Minimal 3-3-1 Model
In this work, we present a general review of neutrino physics in the minimal 331 model. New gauge and scalar interactions are present, with violation of both flavor and lepton numbers.

This review summarizes recent experimental and theoretical progress in determining neutrino mixing angles and masses through neutrino oscillations. We describe the basic physics of oscillation phenomena in vacuum and matter, as well as the status of solar, reactor, atmospheric, and accelerator neutrino experiments that probe these phenomena.

The Standard Model of particle physics fails to explain the important pieces in the standard cosmology, such as inflation, baryogenesis, and dark matter of the Universe. We consider the possibility that the sector to generate small neutrino masses is responsible for all of them; the inflation is driven by the Higgs field to break $B-L$ gauge symmetry ...

Axion–Sterile Neutrino Dark Matter
Extending the standard model with three right-handed neutrinos and a simple QCD axion sector can account for neutrino oscillations, dark matter and baryon asymmetry; at the same time, it solves the strong CP problem, stabilizes the electroweak vacuum and

Non-universal gravitational couplings of neutrinos in matter [PDF]
When neutrinos travel through a normal matter medium, the electron neutrinos couple differently to gravity compared to the other neutrinos, due to the presence of electrons in the medium and the absence of the other charged leptons.

Neutrino mixing and neutrino telescopes [PDF]
Measuring flux ratios of ultra-high energy neutrinos is an alternative method to determine the neutrino mixing angles and the CP phase delta. We conduct a systematic analysis of the neutrino mixing probabilities and of various flux ratios measurable at neutrino telescopes.

Status of Neutrino Properties and Future Prospects—Cosmological and Astrophysical Constraints
Cosmological observations are a powerful probe of neutrino properties, and in particular of their mass. In this review, we first discuss the role of neutrinos in shaping the cosmological evolution at both the background and perturbation level, and ...

Gravitational Lensing of Supernova Neutrino Bursts
Supernova neutrino bursts have been observed from extragalactic distances. This note addresses the question of how gravitational lensing could distort the information in the burst.
