Abstract

Motivated by recent experimental data, we study solar neutrino oscillations in the range 10^-10 < delta m²/E < 10^-7 eV²/MeV. In this range vacuum oscillations become increasingly affected by (solar and terrestrial) matter effects for increasing delta m², smoothly reaching the MSW regime. A numerical study of matter effects in such "quasi-vacuum" regime is performed. The results are applied to the analysis of the recent solar neutrino phenomenology.
