doi:10.1103/PhysRevD.105.012004, We report the first direct measurement of the inclusive branching fraction $\mathcal B (B_s \to D_sX)$ via $B_s$ tagging in $e^+e^��� ��� ��(5S)$ events. Tagging is accomplished through a partial reconstruction of semileptonic decays $B_s ��� D_sX�����$, where X denotes unreconstructed additional hadrons or photons and $���$ is an electron or muon. With 121.4 fb$^{���1}$ of data collected at the $��(5S)$ resonance by the Belle detector at the KEKB asymmetric-energy $e^+e^���$ collider, we obtain $\mathcal B (B_s \to D_sX)=(60.2��5.8��2.3)%$, where the first uncertainty is statistical and the second is systematic.
