Just-So Oscillation: as Just as MSW?

, 1995
The neutrino long wavelength (just-so) oscillation is reconsidered as a solution to the solar neutrino problem. In the light of the presently updated results of the four solar neutrino experiments, the data fit in the just-so scenario substantially ...

TeV Right-handed Neutrinos and the Flavor-symmetry-improved Seesaw Mechanism [PDF]

, 1996
Horizontal flavor symmetries can drastically suppress Dirac neutrino masses well below those of the corresponding charged leptons. We show that models can be constructed where the light neutrino mass eigenvalues are small enough to give the MSW solution ...

Nuclear astrophysicists at war

Natural Sciences, Volume 4, Issue 1, January 2024.
The Manhattan program not only opened the path to the nuclear age for humans, but also triggered a lot of new questions and research directions in nuclear physics and astrophysics that still inform the ideas in these fields today. Abstract The question of energy production in stars stimulated an entire generation of young physicists in the 1930s who ...

Global Analysis of the post-SNO Solar Neutrino Data for Standard and Non-Standard Oscillation Mechanisms

, 2002
What can we learn from solar neutrino observations? Is there any solution to the solar neutrino anomaly which is favored by the present experimental panorama? After SNO results, is it possible to affirm that neutrinos have mass?

THE CHARGED NEUTRINO: A NEW APPROACH TO THE SOLAR NEUTRINO PROBLEM [PDF]

Modern Physics Letters A, 1994
We have considered the effect of the reduction of the solar neutrino flux on earth due to the deflection of the charged neutrino by the magnetic field of the solar convective zone. The antisymmetry of this magnetic field about the plane of the solar equator induces the anisotropy of the solar neutrino flux thus creating the deficit of the neutrino ...

A Broad Set of Solar and Cosmochemical Data Indicates High C-N-O Abundances for the Solar System

The Astrophysical Journal
We examine the role of refractory organics as a major C carrier in the outer protosolar nebula and its implications for the compositions of large Kuiper Belt objects (KBOs) and CI chondrites.

Mixing and the solar neutrino problem

The Astrophysical Journal, 1990
Evolutionary sequences for the sun were calculated assuming continuous or episodic mixing of matter in the solar interior. The ad hoc mixing affects solar neutrino emission because it increases the interior H-1 and He-3 content and reduces the temperature at the solar center.

Effect of Coulomb collisions on time variations of the solar neutrino flux

, 1999
We consider the possibility of time variations of the solar neutrino flux due to the radial motion of the Earth and neutrino interference effects. We calculate the time variations of the detected neutrino flux and the extent to which they are suppressed ...

An Expanded Set of Los Alamos OPLIB Tables in MESA: Type-1 Rosseland-mean Opacities and Solar Models

The Astrophysical Journal
We present a set of 1194 Type-1 Rosseland-mean opacity tables for four different metallicity mixtures. These new Los Alamos OPLIB atomic radiative opacity tables are an order of magnitude larger in number than any previous opacity table release, and span

Axino as a sterile neutrino and R parity violation [PDF]

, 2001
We point out that axino can be a natural candidate for sterile neutrino which would accommodate the LSND data with atmospheric and solar neutrino oscillations.
