Magnus approximation in neutrino oscillations

Neutrino oscillations

founded in 1739, is an independent organisation whose overall objective is to promote the sciences and strengthen their influence in society. The Academy takes special responsibility for the natural sciences and mathematics, but endeavours to promote the exchange of ideas between various disciplines.

neutrino oscillations

The original B. Pontecorvo idea of neutrino oscillations is discussed. Neutrino mixing and basics of neutrino oscillations in vacuum and in matter are considered. Recent evidences in favour of neutrino oscillations, obtained in the Super-Kamiokande, SNO, KamLAND and other neutrino experiments are discussed. Neutrino oscillations in the solar and atmospheric ranges of the neutrino mass-squared d...

Gravitational Correction in Neutrino Oscillations

Recently, the neutrino oscillation phase due to the presence of gravity is much discussed [1], [2], [3]. If the neutrinos are massive particles and mixed, the neutrino oscillation between different flavor states occurs. Suppose that neutrinos are created as weak flavor eigenstate, say, at ~rA, and propagate to ~rB . The state is a linear superposition of mass eigenstates and each phase of mass ...

Atmospheric Neutrino Oscillations in Macro

In this paper we first give a short overview of the MACRO detector which was operational at the Gran Sasso Laboratory from 1989 till the end of 2000. Then we present and discuss the results on atmospheric muon neutrino oscillations, concerning medium (∼ 4 GeV) and high (∼ 50 GeV) energy data. Using the Multiple Coulomb Scattering of muons inside the lower part of the detector, estimates of neut...
