A Short Review on the Latest Neutrinos Mass and Number Constraints from Cosmological Observables

open access: yesUniverse, 2022
We review the neutrino science, focusing on its impact on cosmology along with the latest constraints on its mass and number of species. We also discuss its status as a possible solution to some of the recent cosmological tensions, such as the Hubble ...

Energy and Momentum of Oscillating Neutrinos [PDF]

open access: yes, 2001
It is shown that Lorentz invariance implies that in general flavor neutrinos in oscillation experiments are superpositions of massive neutrinos with different energies and different momenta.

Multimessenger Search for the Sources of Cosmic Rays Using Cosmic Neutrinos

open access: yesFrontiers in Astronomy and Space Sciences, 2019
After updating the status of the measurements of the cosmic neutrino flux by the IceCube experiment, we summarize the evidence for the first identified source of cosmic rays and speculate on the connection between the two observations.

Atmospheric leptons, the search for a prompt component [PDF]

open access: yes, 2013
The flux of high-energy (>GeV) neutrinos consists primarily of those produced by cosmic-ray interactions in the atmosphere. The contribution from extraterrestrial sources is still unknown. Current limits suggest that the observed spectrum is dominated by

Neutrino masses [PDF]

open access: yesAnnalen der Physik, 2013
The various experiments on neutrino oscillation evidence that neutrinos have indeed non‐zero masses but cannot provide the absolute neutrino mass scale. This scale of neutrino masses is very important for understanding the evolution and the structure formation of the universe as well as for nuclear and particle physics beyond the present Standard Model.

Solar neutrinos [PDF]

open access: yesAIP Conference Proceedings, 1966
The predicted capture rate in the Cl37 experiment for detecting solar neutrinos is calculated using the results of recent nuclear experiments and solar-model investigations. It is shown that additional experiments (e.g., with H2, Li7, B11, or ν-e scattering) are necessary to establish the relative contributions of the proton-proton chain and the CNO ...

Theoretical Search for Gravitational Bound States of Tachyons

open access: yesParticles, 2022
The mission here is to see if we can find bound states for tachyons in some gravitational environment. That could provide an explanation for the phenomena called Dark Matter. Starting with the standard Schwarzschild metric in General Relativity, which is

Sterile neutrinos with pseudoscalar self-interactions and cosmology [PDF]

open access: yes, 2015
Sterile neutrinos in the electronvolt mass range are hinted at by a number of terrestrial neutrino experiments. However, such neutrinos are highly incompatible with data from the Cosmic Microwave Background and large scale structure. This paper discusses

Ultrahigh Energy Tau Neutrinos [PDF]

open access: yes, 2005
We study ultrahigh energy astrophysical neutrinos and the contribution of tau neutrinos from neutrino oscillations, relative to the contribution of the other flavors.

Neutrino masses and solar neutrinos [PDF]

open access: yesPhysical Review D, 1992
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).
