Recent results from the DANSS experiment

Recent results from the DANSS experiment on the searches for sterile neutrinos are presented. They are based on approximately 5.5 million inverse beta decay events collected at 10.9, 11.9 and 12.9[Formula: see text]m from the reactor core of the 3.1 GW Kalinin Nuclear Power Plant in Russia. We do not see any statistically significant sign for the [Formula: see text] oscillations. The exclusion area in the sterile neutrino oscillation parameters [Formula: see text], [Formula: see text] goes up to [Formula: see text] in the most sensitive region in the reactor model independent study. A comparison of the absolute neutrino event rate and reactor models predictions allowed to exclude practically the whole sterile neutrino parameter space preferred by the BEST experiment as well as the best fit point of the Neutrino-4 experiment. Studies of the positron energy spectrum in the antineutrino inverse beta decay reaction and its dependence on the fuel composition are also presented. The ratio of the cross sections for [Formula: see text]U and [Formula: see text]Pu was measured. Reactor power was measured remotely using antineutrinos with [Formula: see text] accuracy in 3 days during 6.5 years.
