Histogram of multiplicity 2 (M2) events; see text for more details. The spectrum accounts for M2 events that survived quality cuts as well as muon and LAr vetoes. The inset shows the data in the γ-window (blue band) inspected for the nucleon decay signal, i.e. Eγ±12.5 keV with Eγ265.0 keV (gray dashed line)
