\begin{document}$ \times $\end{document}day data in the CDEX-10 experiment assuming that DM is boosted by cosmic rays. For the DM mass range 1 keV \begin{document}$ <m_\chi < $\end{document} 1 MeV and the effective distance within 1 kpc, we reach an almost flat floor limit at \begin{document}$ 8.32\times10^{-30} $\end{document} cm2 for the spin-independent DM–nucleon scattering cross section, at a 90% confidence level. The CDEX-10 result is able to close the gap unambiguously in the parameter space between the MiniBooNE and XENON1T constraints, which were partially hindered by the Earth attenuation effect. We also quantitatively calculate the expected neutrino floor on searching for CRBDM in future direct detection experiments using Germanium."> Constraints on cosmic-ray boosted dark matter in CDEX-10 -
