Search for high-mass dilepton resonances using 139 fb−1 of pp collision data collected at s√=13 TeV with the ATLAS detector Aad, G. Aguilar Saavedra, Juan Antonio Atlas Collaboration A search for high-mass dielectron and dimuon resonances in the mass range of 250 GeV to 6 TeV is presented. The data were recorded by the ATLAS experiment in proton-proton collisions at a centre-of-mass energy of s√=13 TeV during Run 2 of the Large Hadron Collider and correspond to an integrated luminosity of 139 fb−1. A functional form is fitted to the dilepton invariant-mass distribution to model the contribution from background processes, and a generic signal shape is used to determine the significance of observed deviations from this background estimate. No significant deviation is observed and upper limits are placed at the 95% confidence level on the fiducial cross-section times branching ratio for various resonance width hypotheses. The derived limits are shown to be applicable to spin-0, spin-1 and spin-2 signal hypotheses. For a set of benchmark models, the limits are converted into lower limits on the resonance mass and reach 4.5 TeV for the E6-motivated Z′ψ boson. Also presented are limits on Heavy Vector Triplet model couplings. 2020-04-29T11:45:29Z 2020-04-29T11:45:29Z 2019-07-10 journal article Aad, G., Kupco, A., Webb, S., Dreyer, T., Wang, Y., Jakobs, K., ... & Schovancova, J.
