Parity violation and chiral oscillation of cosmological relic neutrinos

Physics Letters B, 2020
The conventional derivation of neutrino oscillation treats neutrino mass eigenstate as plane wave with an overall evolution phase. Nevertheless, due to the intrinsic parity-violating nature of weak interactions, only the left-chiral neutrino can be ...

Effects of gravitational lensing on neutrino oscillation in $$ \gamma $$ γ -spacetime

European Physical Journal C: Particles and Fields, 2022
We study the effects of gravitational lensing on neutrino oscillations in the $$\gamma $$ γ -spacetime which describes a static, axially-symmetric and asymptotically flat solution of the Einstein’s field equations in vacuum.

Neutrino mass spectrum and neutrinoless double beta decay [PDF]

, 2000
The relations between the effective Majorana mass of the electron neutrino, $m_{ee}$, responsible for neutrinoless double beta decay, and the neutrino oscillation parameters are considered.

Disentangling neutrino oscillations

Physics Letters B, 2009
The theory underlying neutrino oscillations has been described at length in the literature. The neutrino state produced by a weak decay is usually portrayed as a linear superposition of mass eigenstates with, variously, equal energies or equal momenta. We point out that such a description is incomplete, that in fact, the neutrino is entangled with the ...

A search for neutrino oscillations [PDF]

Zeitschrift f�r Physik C Particles and Fields, 1988
We present here the final results of experiments searching for neutrino oscillations, carried out by the CHARM Collaboration. The data — taking took place in 1983. The first experiment was performed by exposing two detectors simultaneously to the CERN PS low energyvµ beam.

Uncertainties in the oscillation parameters measurement due to multi-nucleon effects at NOνA experiment

Nuclear Physics B, 2022
In this work, we investigate the role of multi-nucleon (MN) effects (mainly 2p-2h and RPA) on the sensitivity measurement of various neutrino oscillation parameters, in the disappearance channel of NOνA (USA) experiment.

Entanglement in neutrino oscillations [PDF]

EPL (Europhysics Letters), 2009
Flavor oscillations in elementary particle physics are related to multi-mode entanglement of single-particle states. We show that mode entanglement can be expressed in terms of flavor transition probabilities, and therefore that single-particle entangled states acquire a precise operational characterization in the context of particle mixing.

CP Violation and Matter Effect in Long Baseline Neutrino Oscillation Experiments [PDF]

, 1997
We show simple methods how to separate pure CP violating effect from matter effect in long baseline neutrino oscillation experiments with three generations of neutrinos.

Paradoxes of neutrino oscillations [PDF]

Physics of Atomic Nuclei, 2009
Despite the theory of neutrino oscillations being rather old, some of its basic issues are still being debated in the literature. We discuss, in the framework of the wave packet approach, a number of such issues, including the relevance of the "same energy" and "same momentum" assumptions, the role of quantum-mechanical uncertainty relations in ...

Teaching neutrino oscillations [PDF]

American Journal of Physics, 2004
Neutrino oscillations are purely quantum mechanical effects that occur over macroscopic time and distance scales. I present the physics of this phenomenon in words, pictures, and analogies rather than mathematics.
