| contents | A search for a new $Z'$ gauge boson predicted by $L_μ-L_τ$ models, based on charged-current Drell-Yan production, $pp \rightarrow W^{\pm(*)} \rightarrow Z' μ^{\pm} ν\rightarrow μ^{\pm}μ^{\mp}μ^{\pm}ν$, is presented. The data sample used corresponds to an integrated luminosity of 140 fb$^{-1}$ of proton-proton collisions at $\sqrt{s} = 13$ TeV recorded by the ATLAS detector at the Large Hadron Collider. The search examines a final state of $3μ$ plus large missing transverse momentum. Upper limits are set on the $Z'$ production cross-section times branching ratio in the mass range of 5-81 GeV. After combining with the previous $Z'$ search using the neutral-current Drell-Yan production with a $4μ$ final state, the most stringent exclusion limits to date are achieved in the parameter space of the $Z'$ coupling strength and mass. |
