Search for sterile neutrinos on the Gallium Germanium Neutrino Telescope with artificial neutrino sources in the BEST experiment

The possibility of the BEST experiment on electron neutrino disappearance with intense artificial sources of electron neutrino ⁵¹Cr is considered. BEST has the great potential to search for transitions of active neutrinos to sterile states with Δ m ² ∼1 eV² and to set the limits on short baseline electron neutrino disappearance oscillation parameters. The possibility of the further constraints the oscillation parameters region with using ⁶⁵Zn source is discussed. (paper)
