Abstract

Parameters of the model involving three active and three sterile neutrinos are estimated. Specifically, these are the parameters of mixing of active and sterile neutrinos and mass parameters of sterile neutrinos. In doing this, use is made of the results of the BEST (Baksan Experiment on Sterile Transitions) experiment. The BEST experiment is aimed at testing the gallium anomaly at short distance—that is, the deficit of electron neutrinos from a radioactive source. In addition, the results of experiments devoted to testing the accelerator and reactor anomalies at short distances are taken into account along with some astrophysical data.
