A Short Review on the Latest Neutrinos Mass and Number Constraints from Cosmological Observables
Universe, 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]
, 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
Frontiers 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]
, 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

Annalen 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.

Theoretical Search for Gravitational Bound States of Tachyons
Particles, 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

AIP 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 ...

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

Equation of State and Composition of Proto-Neutron Stars and Merger Remnants with Hyperons
Universe, 2021 Finite-temperature equation of state (EoS) and the composition of dense nuclear and hypernuclear matter under conditions characteristic of neutron star binary merger remnants and supernovas are discussed.

Momentum-dependent contributions to the gravitational coupling of neutrinos in a medium [PDF]
, 2000 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.
