DESCRIPTION:Speakers: Natalia Skrobova (ITEP\, LPI\, MIPT)\nDANSS is a one
  cubic meter highly segmented solid scintillator detector. It consists of 
 2500 scintillator strips\, covered with gadolinium loaded reflective coati
 ng and read out with SiPMs via wavelength shifting fibers. DANSS is placed
  under a 3 GW industrial reactor at the Kalinin NPP (Russia) on a movable 
 platform. The distance from the reactor core center is varied from 10.7 m 
 to 12.7 m on-line. The inverse beta decay (IBD) process is used to detect 
 antineutrinos. DANSS detects about 5000 IBD events per day with the backgr
 ound from cosmic muons at the level of few percent.\nSterile neutrinos are
  searched for assuming a 4 neutrino model (3 active and 1 sterile neutrino
 ). The exclusion area in the sterile neutrino parameter plane is obtained 
 using a ratio of positron energy spectra collected at different distances.
  Therefore results do not depend on the shape and normalization of the rea
 ctor νe spectrum\, as well as on the detector efficiency. The excluded ar
 ea covers a wide range of the sterile neutrino parameters up to $sin2\\the
 ta^{2}$ \n\nhttps://indico.particle.mephi.ru/event/22/contributions/1330/
