Search for a new Z' gauge boson via the 𝑝𝑝 → 𝑊±(*) → 𝑍′𝜇±𝜈 → 𝜇±𝜇∓𝜇±𝜈 process in pp collisions at √s= 13 TeV with the ATLAS detector
A search for a new 𝑍′ gauge boson predicted by 𝐿𝜇 −𝐿𝜏 models, based on charged-current Drell-Yan production, 𝑝𝑝 →𝑊±(*) →𝑍′𝜇±𝜈 →𝜇±𝜇∓𝜇±𝜈, is presented. The data sample used corresponds to an integrated luminosity of 140 fb−1 of proton-proton collisions at √𝑠 =13 TeV recorded by the ATLAS detecto...

| Zusammenfassung: | A search for a new 𝑍′ gauge boson predicted by 𝐿𝜇 −𝐿𝜏 models, based on charged-current Drell-Yan production, 𝑝𝑝 →𝑊±(*) →𝑍′𝜇±𝜈 →𝜇±𝜇∓𝜇±𝜈, is presented. The data sample used corresponds to an integrated luminosity of 140 fb−1 of proton-proton collisions at √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. |
