Search for Minimal Supersymmetric Standard Model Higgs bosons H/A and for a Z′ boson in the ττ final state at √s=13TeV with the ATLAS Detector — •Dirk Duschinger, Lorenz Hauswald, Wolfgang Mader, and Arno Straessner — Institut fuer Kern und Teilchenphysik, TU-Dresden
Searches for new heavy resonances decaying to tau-lepton pairs are both theoretically and experimentally well motivated. Extensions of the Standard Model often include additional particles, such as the Minimal Supersymmetric Standard Model (MSSM) introducing new heavy neutral higgs bosons A and H. Many other models commonly include heavy neutral Z′ bosons, some of them predicting preferred couplings to third-generation fermions.
The search for high-mass resonances decaying into τ+τ− final states with the ATLAS detector is presented. The data were recorded in proton-proton collisions at √s = 13 TeV produced by the Large Hadron Collider. The τhadτhad, τµτhad and τeτhad channels are analyzed. The results are interpreted for the MSSM in the hMSSM and mhmod scenarios. Theories including Z′ bosons are studied in the sequential standard model as well as in the non-universal G(221) model.
