Search for additional heavy neutral Higgs and gauge bosons in the ditau final state produced in 36 fb(-1) of pp collisions at root s=13 TeV with the ATLAS detector

Popis výsledku v původním jazyce

A search for heavy neutral Higgs bosons and Z&apos; bosons is performed using a data sample corresponding to an integrated luminosity of 36.1 fb(-1) from proton-proton collisions at root s = 13 TeV recorded by the ATLAS detector at the LHC during 2015 and 2016. The heavy resonance is assumed to decay to tau(+)tau(-) with at least one tau lepton decaying to final states with hadrons and a neutrino. The search is performed in the mass range of 0.2-2.25 TeV for Higgs bosons and 0.2-4.0 TeV for Z&apos; bosons. The data are in good agreement with the background predicted by the Standard Model. The results are interpreted in benchmark scenarios. In the context of the hMSSM scenario, the data exclude tan beta &gt; 1.0 for m(A) = 0.25 TeV and tan beta &gt; 42 for m(A) = 1.5 TeV at the 95% confidence level. For the Sequential Standard Model, Z&apos;(SSM) with m(Z&apos;) &lt; 2.42 TeV is excluded at 95% confidence level, while Z&apos;(NU) with m(Z&apos;) &lt; 2.25 TeV is excluded for the non-universal G(221) model that exhibits enhanced couplings to third-generation fermions.
