TL;DR
This paper reports new experimental constraints on sub-GeV dark matter particles interacting with electrons, derived from ionization data collected by the DarkSide-50 argon detector.
Contribution
It provides the first limits on sub-GeV dark matter-electron scattering using the DarkSide-50 detector data.
Findings
Established new upper limits on dark matter-electron scattering cross section.
Demonstrated the sensitivity of the DarkSide-50 detector to low-mass dark matter.
Constrained parameter space for sub-GeV dark matter models.
Abstract
We present new constraints on sub-GeV dark matter particles scattering off electrons in argon based on an analysis of ionization signal data from the DarkSide-50 detector.
