Analysis of solar neutrino problem by means of Nötzold and Nakagawa's approach including the interference term- Hyperbolic-tangent profile for electron density in the sun and exact solution -

Masahiro Kaneyama, Minoru Biyajima

Using an exact solution with the hyperbolic-tangent profile for the electron density in the sun, which is developed by Nötzold and later modified by Nakagawa, we have analyzed the…
