Fig. 2: Pre-fit DS-20k $${N}_{{e}^{-}}$$ N e − spectra distribution.

The corresponding ER and NR energy scales are indicated at the top. The pre-fit background model (red line) is shown with its uncertainties (shaded area). Contributions from all the components of the background are also shown. A typical signal model is superimposed for illustration (green dotted line), assuming a 2 GeV c−2 WIMP mass with a cross-section of 3 × 10−44 cm2 and quenching fluctuations.
