Search for Top-Philic Heavy Resonances in pp Collisions at *%s=13 TeV with the ATLAS Detector / G.Aad, F.Ahmadov, I.N.Aleksandrov, V.A.Bednyakov, I.R.Boyko, I.A.Budagov, G.A.Chelkov, A.Cheplakov, M.V.Chizhov, D.V.Dedovich, M.Demichev, A.Gongadze, M.I.Gostkin, S.N.Karpov, Z.M.Karpova, U.Kruchonak, V.Kukhtin, E.Ladygin, V.Lyubushkin, T.Lyubushkina, S.Malyukov, M.Mineev, E.Plotnikova, I.N.Potrap, N.A.Rusakovich, M.Shiyakova, A.Soloshenko, S.Turchikhin, T.Turtuvshin, I.Yeletskikh, A.Zhemchugov, N.I.Zimine, Y.Kulchitsky, N.Huseynov, [ATLAS Collab.] // The European Physical Journal C [Electronic resource]. – 2024. – Vol. 84, No. 2. – P. 157. – URL: https://doi.org/10.1140/epjc/s10052-023-12318-9. – Bibliogr.: 103.
A search for the associated production of a heavy resonance with a top-quark or a top-antitop-quark pair, and decaying into a t ¯t pair is presented. The search uses the data recorded by the ATLAS detector in pp collisions at √s = 13 TeV at the Large Hadron Collider during the years 2015–2018, corresponding to an integrated luminosity of 139 fb−1 . Events containing exactly one electron or muon are selected. The two hadronically decaying top quarks from the resonance decay are reconstructed using jets clustered with a large radius parameter of R = 1. The invariant mass spec- trum of the two top quark candidates is used to search for a resonance signal in the range of 1.0 TeV to 3.2 TeV. The pres- ence of a signal is examined using an approach with minimal model dependence followed by a model-dependent interpre- tation. No significant excess is observed over the background expectation. Upper limits on the production cross section times branching ratio at 95% confidence level are provided for a heavy Z ′ boson based on a simplified model, for Z ′ mass between 1.0 TeV and 3.0 TeV. The observed (expected) lim- its range from 21 (14) fb to 119 (86) fb depending on the choice of model parameters
