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.

Time-energy uncertainty relation for neutrino oscillations in curved spacetime [PDF]
Classical and quantum gravity, 2019 We derive the Mandelstam–Tamm time–energy uncertainty relation for neutrino oscillations in a generic stationary curved spacetime. In particular, by resorting to Stodolsky covariant formula of the quantum mechanical phase, we estimate gravity effects on ...

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 ...

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.

Neutrino oscillations in dark backgrounds [PDF]
Proceedings of The 20th International Workshop on Neutrinos — PoS(NuFACT2018), 2018 We examine scenarios in which a dark sector (dark matter, dark radiation, or dark energy) couples to the active neutrinos. For light and weakly-coupled exotic sectors we find that scalar, vector, or tensor dark backgrounds may appreciably impact neutrino

Neutrino Oscillations and Non-standard Interactions [PDF]
Frontiers of Physics, 2017 Current neutrino experiments measure the neutrino mixing parameters with an unprecedented accuracy. The upcoming generation of experiments will be sensitive to subdominant effects that can give information on the unknown neutrino parameters: the Dirac CP-

Quantifying quantum coherence in experimentally observed neutrino oscillations [PDF]
Physical Review A, 2018 Neutrino oscillation represents an intriguing physical phenomenon where the quantumness can be maintained and detected over a long distance. Previously, the nonclassical character of neutrino oscillation was tested with the Leggett-Garg inequality, where

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.

Normal-mode analysis for collective neutrino oscillations [PDF]
Journal of Cosmology and Astroparticle Physics, 2018 In an interacting neutrino gas, collective modes of flavor coherence emerge that can be propagating or unstable. We derive the general dispersion relation in the linear regime that depends on the neutrino energy and angle distribution.

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 ...
