CP-phase effects on the effective neutrino mass in the case of quasi-degenerate neutrinos
J. Maalampi, J. Riittinen
We study the possibility that the three mass states of the ordinary active neutrinos actually split into pairs of quasi-degenerate states, with eV or…
Sterile neutrino signals from supernovae
P. Keränen, J. Maalampi, M. Myyryläinen +1
We investigate the effects of a mixing of active and sterile neutrinos on the ratios of supernova electron neutrino flux () and antineutrino flux () to the total f…
Landau-Zener problem in a three-level neutrino system with non-linear time dependence
P. Keränen, J. Maalampi, M. Myyryläinen +1
We consider the level-crossing problem in a three-level system with non-linearly time-varying Hamiltonian (time-dependence ). We study the validity of the so-called indepen…
Effects of degenerate sterile neutrinos on the supernova neutrino flux
P. Keranen, J. Maalampi, M. Myyrylainen +1
We consider the possibility that there exist sterile neutrinos which are closely degenerate in mass with the active neutrinos and mixed with them. We investigate the effects of thi…
Effects of sterile neutrinos on the ultrahigh-energy cosmic neutrino flux
P. Keranen, J. Maalampi, M. Myyrylainen +1
We investigate the effect of sterile neutrinos that are nearly degenerate with active ones on the flux of ultrahigh-energy cosmic ray neutrinos at earth. This offers a way to probe…
