Abstract

Searches for mass-3 component in the electron neutrino flavor state sinθ13 and for sterile neutrinos can be carried out in the same small mixing angle antineutrino oscillation experiment at a reactor. As an example we consider a layout, which involves several movable antineutrino spectrometers, stationed at distances 1700 m - 50 m from a reactor. The experiment can scan neutrino mass parameter interval ∼(0.5-0.001) eV2 and have there typical sensitivity to sin22θ at a level of 0.015-0.02. The signature for sterile neutrino is disappearance observed at mass parameter Δm2new different from Δm2atm ≈ 2× 10-3 eV2. In any case existing constraints both on sinθ13 and on sterile neutrinos can considerably be improved.
