New results from the DANSS experiment

Understand

There are several experimental indications of sterile neutrinos with a mass in the 1 eV ballpark and many experiments are trying to clarify the situation.

• During 6 years the DANSS experiment collected more than 6 million Inverse Beta Decay (IBD) events and measured the background level during 4 reactor-off periods.
• Data were collected at 3 distances (10.9 m, 11.9 m, and 12.9 m) from the center of the core of a 3.1 GW$_{th}$ reactor with event rate up to 5 thousand per day.
• The detector position was changed frequently usually 2-3 times a week.
