Author(s): R. Aaij et al. (LHCb Collaboration) A measurement of the flavor-untagged decay-time-integrated $CP$ asymmetry in the flavor-specific decay ${B}_{s}^{0}→{D}_{s}^{−}{π}^{+}$, $⟨{A}_{\text{untagged}}^{s}⟩$, is performed using proton-proton collision data collected by the LHCb experiment between 2016 and 2018 at a center-of-mass energy of… [Phys.
