\begin{document}$\chi$\end{document} annihilates into a pair of on-shell particles \begin{document}$\phi$\end{document}, which subsequently decay into the \begin{document}$\psi \psi$\end{document} final state; \begin{document}$\psi$\end{document} interacts with electrons to generate the observed excess events. Because of the mass hierarchy, the velocity of \begin{document}$\psi$\end{document} can be rather large and can have an extended distribution, providing a good fit to the electron recoil energy spectrum. We estimate the flux of \begin{document}$\psi$\end{document} from dark matter annihilations in the galaxy and further determine the interaction cross section, which is sizable but sufficiently small to allow \begin{document}$\psi$\end{document} to penetrate the rocks to reach the underground labs."> On-shell mediator dark matter models and the Xenon1T excess -
