Description
The COHERENT collaboration performed a reanalysis of the data collected at Oak Ridge National Laboratory's Spallation Neutron Source with its high-purity germanium detector array, Ge-mini. Reanalysis of the "Campaign-2" dataset was motivated by the successful analysis of the "Campaign-3" dataset; which extended coherent elastic neutrino–nucleus scattering (CEvNS) measurements in Ge-mini to a lower energy threshold with improved noise understanding and timing reconstruction, and reduced backgrounds through newly-implemented pulse-shape discrimination techniques. The increased statistics and stronger signal-to-noise ratio from this reanalysis allow for a more precise measurement of the CEvNS cross section, an important probe of the standard model.
