Model Independent Information On Solar Neutrino Oscillations [PDF]

open access: yes, 2001
We present the results of a Bayesian analysis of solar neutrino data in terms of nu_e->nu_{mu,tau} oscillations, independent from the Standard Solar Model predictions for the solar neutrino fluxes. We show that such a model independent analysis allows to

The B16 Standard Solar Models

open access: yesJournal of Physics: Conference Series, 2018
We describe a new generation of standard solar models (SSMs), Barcelona 2016 or B16 for short, that includes recent updates on some important nuclear reaction rates, a more consistent treatment of the equation of state and a novel and flexible treatment of opacity uncertainties.

A more realistic representation of overshoot at the base of the solar convective envelope as seen by helioseismology [PDF]

open access: yes, 2011
The stratification near the base of the Sun's convective envelope is governed by processes of convective overshooting and element diffusion, and the region is widely believed to play a key role in the solar dynamo. The stratification in that region gives

New Weinberg operator for neutrino mass and its seesaw origin

open access: yesJournal of High Energy Physics, 2019
We consider a new Weinberg operator for neutrino mass of the form H u H ˜ d L i L j $$ {H}_u{\tilde{H}}_d{L}_i{L}_j $$ involving two different Higgs doublets H u , H d with opposite hypercharge, where H ˜ s d $$ \tilde{H}{s}_d $$ is the charge conjugated

Searches for atmospheric long-lived particles

open access: yesJournal of High Energy Physics, 2020
Long-lived particles are predicted in extensions of the Standard Model that involve relatively light but very weakly interacting sectors. In this paper we consider the possibility that some of these particles are produced in atmospheric cosmic ray ...

Vacuum and MSW interpretations of solar neutrino data with the LNW mass matrix [PDF]

open access: yes, 2000
The Lehmann-Newton-Wu mass matrix, which was recently applied to neutrinos, is further investigated. The analytic results presented earlier are confirmed numerically for the solar density profile of the Standard Solar Model.

Revisiting the standard solar model

open access: yesThe Astrophysical Journal, 1988
The mutual consistency between standard solar models is studied based on the recent Los Alamos opacity tables. Satisfactory agreement is found among these models concerning the helium content and the neutrino capture rates. The reference model leads to a solar helium content of 0.276 + or - 0.012 by mass fraction. 75 references.

Determining the initial helium abundance of the Sun

open access: yes, 2010
We determine the dependence of the initial helium abundance and the present-day helium abundance in the convective envelope of solar models ($\yim$ and $\ysm$ respectively) on the parameters that are used to construct the models.

Bounds on non-standard interactions of neutrinos from IceCube DeepCore data

open access: yesJournal of High Energy Physics, 2020
New physics in neutrino sector can reveal itself via non-standard neutrino in- teractions which can result in modification of the standard picture of neutrino propagation in matter.

The role of electron-screening deformations in solar nuclear fusion reactions and the solar neutrino puzzle [PDF]

open access: yes, 2000
Thermonuclear fusion reaction rates in the solar plasma are enhanced by the presence of the electron cloud that screens fusing nuclei. The present work studies the influence of electron screening deformations on solar reaction rates in the framework of ...
