Query: Production and attenuation of cosmic-ray boosted dark matter   Light sub-GeV halo dark matter (DM) particles up-scattered by high-energy
cosmic-rays (CRs) (referred to as CRDM) can be energetic and become detectable
by conventional DM direct detection experiments. We perform a refined analysis
on the exclusion bounds of the spin-independent DM-nucleon scattering cross
section $\sigma_{\chi p}$ in this approach. For the exclusion lower bounds, we
determine the parameter of the effective distance $D_\text{eff}$ for CRDM
production using spatial-dependent CR fluxes and including the contributions
from the major heavy CR nuclear species. We obtain $D_\text{eff}\simeq 9$ kpc
for CRDM particles with kinetic energy above $\sim 1~\text{GeV}$, which pushes
the corresponding exclusion lower bounds down to $\sigma_{\chi p} \sim 4\times
10^{-32}~\text{cm}^2$ for DM particle mass at MeV scale and below. For the
exclusion upper bounds from Earth attenuation, previous estimations neglecting
the nuclear form factor leaded to typical exclusion upper bounds of
$\sigma_{\chi p}\sim\mathcal{O}(10^{-28})~\text{cm}^2$ from the XENON1T data.
Using both the analytic and numerical approaches, we show that for CRDM
particles, the presence of the nuclear form factor strongly suppresses the
effect of Earth attenuation. Consequently, the cross section that can be
excluded by the XENON1T data can be a few orders of magnitude higher, which
closes the gap in the cross sections excluded by the XENON1T experiment and
that by the astrophysical measurements such that for the cosmic microwave
background (CMB), galactic gas cloud cooling, and structure formation, etc..
