Light sterile neutrinos effects in processes with electron and muon neutrinos

For oscillation processes involving electron and muon neutrinos, as well as for beta decay and neutrinoless double beta decay processes, the contributions of light sterile neutrinos in the characteristics of these processes are calculated. For this, estimates of the mixing parameters in the model with three active and three sterile neutrinos are made taking into account some experimental data. The results obtained can be used for interpretation of available experimental data, and also for predictions of values of new data, which will be registered in ongoing and planned experiments.Comment: 11 pages, 3 figure
