Models of Neutrino Mass and Interactions for Neutrino Oscillations
نویسنده
چکیده
I review the various mechanisms for obtaining nonzero neutrino masses. I focus on the possibility of adding one light singlet neutrino to the three known doublet neutrinos νe, νμ, and ντ to accommodate the totality of neutrino-oscillation experiments. I review the various theoretical suggestions for this singlet. I discuss also a scenario in which there are only the three doublet neutrinos but a large anomalous interaction is assumed for ντ as an attempt to explain all present data.

An extremely light scalar weakly interacting with light neutrinos has interesting consequences in stellar evolution, neutrino oscillations and laboratory neutrino mass measurements. In this paper we construct realistic gauge models for such scalar-neutrino interactions.

متن کاملNeutrino Mixing , Cp / T Violation and Textures in Four - Neutrino Models
We examine the prospects for determining the neutrino mixing matrix and for observing CP and T violation in neutrino oscillations in four-neutrino models. We focus on a general class of four-neutrino models with two pairs of nearly degenerate mass eigenstates separated by approximately 1 eV, which can describe the solar, atmospheric and LSND neutrino data. We present a general parametrization o...
متن کاملOverview of Neutrino Oscillation Physics *
Recent evidence for neutrino oscillations has revolutionized the study of neutrino masses and mixing. This report gives an overview of what we are learning from the neutrino oscillation experiments, the prospects for the near term, and the bright future of neutrino mass studies. Tree-level mass generation occurs through the Higgs mechanism. The Dirac mass m D arises in a lepton conserving (∆L =...
متن کاملNeutrino oscillations as a probe of dark energy.
We consider a class of theories in which neutrino masses depend significantly on environment, as a result of interactions with the dark sector. Such theories of mass varying neutrinos were recently introduced to explain the origin of the cosmological dark energy density and why its magnitude is apparently coincidental with that of neutrino mass splittings. In this Letter we argue that in such t...
