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.

Generalized mass ordering degeneracy in neutrino oscillation experiments [PDF]
, 2016 We consider the impact of neutral-current (NC) nonstandard neutrino interactions (NSI) on the determination of the neutrino mass ordering. We show that in the presence of NSI there is an exact degeneracy which makes it impossible to determine the ...

Parameter Limits for Neutrino Oscillation with Decoherence in KamLAND [PDF]
, 2016 In the framework of quantum open systems we analyze data from KamLAND by using a model that considers neutrino oscillation in a three-family approximation with the inclusion of the decoherence effect.

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.

Neutrino flavor relaxation or neutrino oscillations? [PDF]
Journal of Experimental and Theoretical Physics Letters, 2004 We propose the new mechanism of neutrino flavour relaxation to explain the experimentally observed changes of initial neutrino flavour fluxes. The test of neutrino relaxation hypothesis is presented, using the data of modern reactor, solar and accelerator experiments. The final choice between the standard neutrino oscillations and the proposed neutrino

A framework for testing leptonic unitarity by neutrino oscillation experiments [PDF]
, 2016 A bstractIf leptonic unitarity is violated by new physics at an energy scale much lower than the electroweak scale, which we call low-scale unitarity violation, it has different characteristic features from those expected in unitarity violation at high ...

Majorana neutrino masses and neutrino oscillations [PDF]
Physical Review D, 2001 We examine some patterns of Majorana neutrino mass matrix which is compatible with the phenomenological lepton flavor mixing matrix and non-observation of neutrinoless double beta decay. Imposing $(M_ )_{ee}=0$ for the Majorana neutrino mass matrix in the leading order, we obtain a relationship between the solar mixing angle and the neutrino masses ...

Systematic uncertainties in long-baseline neutrino-oscillation experiments [PDF]
, 2016 Future neutrino-oscillation experiments are expected to bring definite answers to the questions of neutrino-mass hierarchy and violation of charge-parity symmetry in the lepton sector.

Majorana CP violation insights from decaying neutrinos
Nuclear Physics BIt is well-known that within the standard three flavor neutrino oscillation formalism, the Majorana phases appearing in the neutrino mixing matrix cannot have any effect on neutrino oscillation probabilities thereby evading testability at neutrino ...
