Search for Heavy Higgs Bosons Decaying into Two Tau Leptons with the ATLAS Detector Using pp Collisions at ffiffi s p = 13 TeV Aad, G. Atlas Collaboration, / Aguilar Saavedra, Juan Antonio A search for heavy neutral Higgs bosons is performed using the LHC Run 2 data, corresponding to an integrated luminosity of 139 fb−1 of proton-proton collisions at ffiffi s p ¼ 13 TeV recorded with the ATLAS detector. The search for heavy resonances is performed over the mass range 0.2–2.5 TeV for the τþτ− decay with at least one τ-lepton decaying into final states with hadrons. The data are in good agreement with the background prediction of the standard model. In the M125 h scenario of the minimal supersymmetric standard model, values of tan β > 8 and tan β > 21 are excluded at the 95% confidence level for neutral Higgs boson masses of 1.0 and 1.5 TeV, respectively, where tan β is the ratio of the vacuum expectation values of the two Higgs doublets. 2020-09-28T10:52:55Z 2020-09-28T10:52:55Z 2020-07-27 info:eu-repo/semantics/article Aad, G., Kupco, A., Dreyer, T., Wang, Y., Jakobs, K., Le, B., ... & Schovancova, J.
