[@Sirunyan:2018]. We require the origin of electron and muon candidates to be consistent with the PV. Restrictions are imposed on the magnitude of the impact parameters of their tracks relative to the PV in the transverse plane ([$d_{xy}$]{}), and on the longitudinal displacement ([$d_{z}$]{}) of the point of closest approach. To ensure that electron or muon candidates are isolated from jet activity, we define a relative isolation quantity ([$I_{\text{rel}}$]{}) as the ratio of the scalar sum of hadron and photon PF candidates, in an $\eta$-$\phi$ cone of radius 0.3 or 0.4 around the candidate electron or muon, to the candidate , requiring it to be below an upper bound appropriate for the selection. The quantity [$I_{\text{rel}}$]{}is adjusted to account for the contributions of particles originating from pileup interactions. The electron and muon selection criteria applied in the analysis are the same as those described in Ref. [@Sirunyan:2018vig].

The candidates are reconstructed using the CMS hadrons-plus-strips algorithm [@Sirunyan:2018pgf]. The constituents of the reconstructed jets are used to identify individual lepton decay modes with one charged hadron and up to two neutral pions, or three charged hadrons. The candidate momentum is determined from the reconstructed visible lepton decay products. The presence of
