\begin{document}$ b\to s\mu^+\mu^- $\end{document} anomaly and dark matter observables, we study the capability of the LHC to test dark matter, \begin{document}$ Z^{\prime} $\end{document}, and a vector-like quark. We focus on a local \begin{document}$ U(1)_{L_\mu-L_\tau} $\end{document} model with a vector-like \begin{document}$ SU(2)_L $\end{document} doublet quark Q and a complex singlet scalar whose lightest component \begin{document}$ X_I $\end{document} is a candidate of dark matter. After imposing relevant constraints, we find that the \begin{document}$ b\to s\mu^+\mu^- $\end{document} anomaly and the relic abundance of dark matter favor \begin{document}$ m_{X_I}< 350 $\end{document} GeV and \begin{document}$ m_{Z^{\prime}}< 450 $\end{document} GeV for \begin{document}$ m_Q< $\end{document} 2 TeV and \begin{document}$ m_{X_R}< $\end{document} 2 TeV (the heavy partner of \begin{document}$ m_{X_I} $\end{document}). Current searches for jets and missing transverse momentum at the LHC sizably reduce the mass ranges of the vector-like quark, and \begin{document}$ m_Q $\end{document} is required to be larger than 1.7 TeV. Finally, we discuss the possibility of probing these new particles at the high luminosity LHC via the QCD process \begin{document}$ pp \to D\bar{D} $\end{document} followed by\begin{document}$ D\to s (b) X_I $\end{document} , \begin{document}$ D\to s (b) Z'X_I $\end{document}, and then \begin{document}$ Z'\to $\end{document}\begin{document}$ \mu^+\mu^- $\end{document}. Taking a benchmark point of \begin{document}$ m_Q $\end{document} = 1.93 TeV, \begin{document}$ m_{Z^\prime} = 170 $\end{document} GeV, and \begin{document}$ m_{X_I} = $\end{document} 145 GeV, we perform a detailed Monte Carlo simulation and find that this benchmark point can be accessed at the 14 TeV LHC with an integrated luminosity of 3000 fb\begin{document}$ ^{-1} $\end{document}."> Dark matter, <i>Z</i>′, and vector-like quark at the LHC and <i>b</i> → <i>sμμ</i> anomaly -
