Neutrino Mixing and Leptonic CP Phase in Neutrino Oscillations [PDF]

open access: yes, 2001
Oscillations of the Dirac neutrinos of three generations in vacuum are considered with allowance made for the effect of the CP-violating leptonic phase (analogue of the quark CP phase) in the lepton mixing matrix.

Transition Probabilities Of Astrophysical Interest In The Niobium Ions Nb+ And Nb2+ [PDF]

open access: yes, 2010
Aims. We attempt to derive accurate transition probabilities for astrophysically interesting spectral lines of Nb II and Nb III and determine the niobium abundance in the Sun and metal-poor stars rich in neutron-capture elements. Methods.

Resonance enhancement of neutrino oscillations due to transition magnetic moments

open access: yes, 2020
Studying neutrino propagation in static background of dense matter and electromagnetic field [1] we obtained that the resonance enhancement of neutrino oscillations due to transition magnetic moments is possible.

High-Energy Neutrino Flavor State Transition Probabilities

open access: yesApplied Sciences
We analytically determine neutrino transitional probabilities and abundance ratios at various distances from the source of creation in several astrophysical contexts, including the Sun, supernovae and cosmic rays.

Improving the Estimation of Markov Transition Probabilities Using Mechanistic-Empirical Models

open access: yesFrontiers in Built Environment, 2017
In many current state-of-the-art bridge management systems, Markov models are used for both the prediction of deterioration and the determination of optimal intervention strategies.

Atomic Data for Astrophysically Important Spectral Lines of Singly Ionized Nitrogen

open access: yesThe Astrophysical Journal
Nitrogen lines are widely observed in astrophysical spectra and provide important diagnostics for plasma properties. In this work, we present extended calculations for accurate energy levels, electric dipole radiative transition parameters, and lifetimes

Some limit theorems for ratios of transition probabilities

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1987
In this paper, infinite dimensional forward convergent stochastic chains have been considered in the framework of [1]. The main result of this paper deals with the observation that the total flow of probability from the C-states to the T-states is very ...
