New results from the DANSS experiment

Understand

We present new preliminary DANSS results based on 3.5 million Inverse Beta Decay (IBD) events collected at 3 distances (10.9 m, 11.9 m, and 12.9 m) from the detector center to the reactor core center.

• The detector position is changed typically 3 times a week.
• Therefore many systematic uncertainties are canceled out.
• A new analysis that uses information about relative IBD counting rates in addition to changes in positron energy spectra shapes is employed.
