The search for heavy resonances is performed over the mass range 0.2-2.5 TeV for the tau(+)tau(-) decay with at least one tau-lepton decaying into final states with hadrons. The data are in good agreement with the background prediction of the standard model. In the M-h(125) scenario of the minimal supersymmetric standard model, values of tan beta > 8 and tan beta > 21 are excluded at the 95% confidence level for neutral Higgs boson masses of 1.0 and 1.5 TeV, respectively, where tan beta is the ratio of the vacuum expectation values of the two Higgs doublets.eninfo:eu-repo/semantics/openAccessHadron CollidersBottom-Quark fusionPair ProductionStandard ModelCross-SectionPlus plusProgramMassesNNLOExtensionSearch for Heavy Higgs Bosons Decaying into Two Tau Leptons with the ATLAS Detector Using pp Collisions at root s=13 TeVArticle2-s2.0-8508915555510.1103/PhysRevLett.125.05180132794886Q1WOS:000552610300004
