Abstract

Abstract The Neutrino-4 collaboration has improved the detector in the first neutrino laboratory at the SM‑3 reactor. We are also creating a new neutrino laboratory at the same reactor to study light sterile neutrinos. In the Neutrino-4 experiment, oscillations at a 2.7σ confidence level have been observed, which is consistent with the gallium anomaly and the BEST experiment result, but contradicts the latest constraints on the oscillation parameters obtained in the STEREO and PROSPECT experiments. The preparation stages and future prospects of the setup have been presented.
