On the MSW ${\nu }_e\to {\nu }_s$ transition solution of the solar neutrino problem

P. I. Krastev, S. T. Petcov, L. Qiuyu

We study the stability of the two--neutrino MSW solution of the solar neutrino problem, corresponding to solar ${\nu }_e$ transitions into sterile neutrino, ${\nu }_e\to {\nu }_s$, with…
