We present a search for electron-recoil signatures from the charged-current absorption of fermionic dark matter using the EXO-200 detector. We report an average electron recoil background rate of 6.8 × 10â»â´ cts kgâ»Â¹ yrâ»Â¹ keVâ»Â¹ above 4 MeV and find no statistically significant excess over our background projection. Using a total ¹³â¶Xe exposure of 234.1 kg yr we exclude new parameter space for the charged-current absorption cross-section for dark matter masses between m_χ = 2.6−11.6 MeV with a minimum of 6 × 10â»âµÂ¹ cm² at 8.3 MeV at the 90% confidence level. ; Published by the American Physical Society under the terms of the Creative Commons Attribution 4.0 International license.
