	abstract = {We report the first detection of the dark matter distribution around 
Lyman break galaxies (LBGs) at high redshift through the Cosmic
Microwave Background (CMB) lensing measurements with the public \{\vphantom{\}}{\textbackslash}it
Planck\vphantom{\{}\} PR3 \${\textbackslash}kappa\$ map. The LBG sample consists of 1,473,106 objects
with the median redshift of \$z {\textbackslash}sim 4\$ that are identified in a total
area of 305 deg\${\textasciicircum}2\$ observed by the Hyper Suprime-Cam (HSC) Strategic
Survey Program (SSP) survey. After careful investigations of systematic
uncertainties, such as contamination from foreground galaxies and Cosmic
Infrared Background (CIB), we obtain the significant detection of the
CMB lensing signal at \$5.1{\textbackslash}sigma\$ that is dominated by 2-halo term
signals of the LBGs. Fitting a simple model consisting of the
Navarro-Frenk-White (NFW) profile and the linear-bias model, we obtain
the typical halo mass of \$3.1{\textasciicircum}\{+9.3\}\_\{-2.8\} {\textbackslash}times 10{\textasciicircum}\{11\} h{\textasciicircum}\{-1\}
M\_{\textbackslash}odot\$. Combining the CMB lensing and galaxy-galaxy clustering signals
on the large scales, we demonstrate the first cosmological analysis at
\$z{\textbackslash}sim4\$ that constrains \$({\textbackslash}Omega\_\{\{{\textbackslash}rm m\}0\}\$, \${\textbackslash}sigma\_8)\$. We find that
our constraint on \${\textbackslash}sigma\_8\$ is roughly consistent with the \{{\textbackslash}it Planck\}
best-fit cosmology, while this \${\textbackslash}sigma\_8\$ constraint is lower than the
\{{\textbackslash}it Planck\} cosmology over the \$1{\textbackslash}sigma\$ level. This study opens up a
new window for constraining cosmological parameters at high redshift by
the combination of CMB and high-\$z\$ galaxies as well as studying the
interplay between galaxy evolution and larges-scale structure at such
high redshift, by upcoming CMB and optical and near-infrared imaging
surveys.},
