The 95% CL upper limits on the branching fraction for the $125~\mathrm{GeV}$ Higgs boson to decay to a pair of dark quarks $\mathcal{B}(\mathrm{H}\to \mathrm{Q_{dark}\overline{Q}{dark}})$ when the dark sector $N{f}=1$, $N_{c}=3$. The dark pion $\pi_{\mathrm{dark}}$ is assumed to decay to a pair of gluons. The upper limits are shown for different dark pion masses $m_{\pi_{\mathrm{dark}}}$ and proper decay lengths $c\tau_{\pi_{\mathrm{dark}}}$, with $\Lambda_{\mathrm{dark}}/m_{\pi_{\mathrm{dark}}}=2.5$, $m_{\rho_{\mathrm{dark}}}/m_{\pi_{\mathrm{dark}}}=2.5$.
