Implications of the XENON1T excess on the dark matter interpretation
A bstract The dark matter interpretation for a recent observation of excessive electron recoil events at the XENON1T detector seems challenging because its velocity is not large enough to give rise to recoiling electrons of $$ \mathcal{O}\left(\mathrm{keV}\right) $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>O</mml:mi> <mml:mfenced> <mml:mi>keV</mml:mi> </mml:mfenced> </mml:math> .
