With a mass at least six orders of magnitudes smaller than the mass of an electron – but non-zero – neutrinos are a clear misfit in the Standard Model of Particle Physics. On the one hand, its tiny mass makes the neutrino one of the most interesting particles, one that might hold the key to physics beyond the Standard Model. On the other hand this minute mass leads to great challenges in its experimental determination. Three approaches are currently pursued: An indirect neutrino mass…

Phenomenology of the Discrete Symmetry Approach to Neutrino Mixing and Leptonic CP Violation
The discovery of neutrino oscillations caused by non-zero neutrino masses and neutrino mixing opened new field of research in particle physics. The impressive experimental progress made in the last
Meaningful Details: the Value of Adding Baseline Dependence to the Neutrino-Dark Matter Effect
The possible effect on the flavour spectra of astronomical neutrinos from a neutrino-dark matter interaction has been investigated for decoherent neutrinos. In this work, we report results calculated
Consequences of Massive Neutrino to Astrophysics and Cosmology
It is now recognized that a neutrino is a massive spin-1/2 particle. Consequently, neutrinoantineutrino pair production and their pair annihilation are theoretically valid processes. The data prove
Neutrino oscillation experiments have shown definite evidence for non-zero neutrino masses. However, these experiments only tell us about neutrino mass differences, and nothing about the absolute
Quantum estimation in neutrino oscillations
In this work, we analyze two-flavor neutrino oscillations within the framework of quantum estimation theory (QET). We compute the quantum Fischer information (QFI) for the mixing angle θ and show
Neutrino masses in an $$SU(4)\otimes U(1)$$-electroweak model with a scalar decuplet
A neutrino mass model is suggested within an $$SU(4)\otimes U(1)$$SU(4)⊗U(1)-electroweak theory. The smallness of neutrino masses can be guaranteed by a seesaw mechanism realized through Yukawa

Fermion production in bouncing cosmologies
We address the issue of fermionic particle creation in cosmological bouncing models governed by General Relativity, but where the bounce itself takes place due to quantum effects. If the energy scale
A topological approach to neutrino masses by using exotic smoothness
In this paper, we will consider a cosmological model with two topological transitions of the space. The smooth 4-dimensional spacetime of the model admits topological transitions of its 3-dimensional


Double Beta Decay, Majorana Neutrinos, and Neutrino Mass
The theoretical and experimental issues relevant to neutrinoless double beta decay are reviewed. The impact that a direct observation of this exotic process would have on elementary particle physics,

We investigate the sensitivity of tritium β-decay experiments for keV-scale sterile neutrinos. Relic sterile neutrinos in the keV mass range can contribute both to the cold and warm dark matter
Relativistic cyclotron radiation detection of tritium decay electrons as a new technique for measuring the neutrino mass
The shape of the beta-decay energy distribution is sensitive to the mass of the electron neutrino. Attempts to measure the endpoint shape of tritium decay have so far seen no distortion from the
Sterile neutrinos as dark matter.
This model is reexamine and it is found that hot, warm, and cold dark matter are all possibilities and the number density of sterile neutrinos is proportional to [mu][sup 2]/M so that the energy density today is independent of M, which is crucial in determining the large scale structure of the Universe.
Neutrino masses and cosmology with Lyman-alpha forest power spectrum
