A precise analytical description of the Earth matter effect on oscillations of low energy neutrinos
A. N. Ioannisian, N. A. Kazarian, A. Yu. Smirnov +1
We present a formalism for the matter effects in the Earth on low energy neutrino fluxes which is both accurate and has all advantages of a full analytic treatment. The oscillation…

Neutrino oscillations in low density medium
A. N. Ioannisian, A. Yu. Smirnov
For the case of small matter effects: , where is the matter potential, we develop the perturbation theory using as the expansion parameter. We…
