The DANSS Experiment: Recent Results and Perspective

The DANSS experiment is a scintillation spectrometer of reactor antineutrinos placed at the Unit 4 reactor of the Kalinin Nuclear Power Plant about 300 km northwest of Moscow. The main fundamental aim of the experiment is search for sterile neutrinos. The experiment was commissioned in April 2016 and regular data taking has been carried out since October 2016. 7.7 million of inverse beta-decay events have been collected by March 2023. A vast exclusion area of the sterile neutrino parameters was set. In the region of the best sensitivity the limit reached sin2θ^2 = 5 ×10^ - 3 . The reactor power has been monitored for 6.5 years. The dispersion that is not related to single measurement statistics is below 0.5
