Experiment Neutrino-4 search for sterile neutrino and results of measurements

Understand

The experiment Neutrino-4 had started in 2014 with a detector model and then was continued with a full-scale detector in 2016 - 2021.

• In this article we describe all steps of preparatory work on this experiment.
• We present all results of the Neutrino-4 experiment with increased statistical accuracy provided to date.
• The experimental setup is constructed to measure the flux and spectrum of the reactor antineutrinos as a function of distance to the center of the active zone of the SM-3 reactor (Dimitrovgrad, Russia) in the range of 6 - 12 meters.
