Search for Neutral MSSM Higgs Bosons in the decay mode H → τ+τ→ τe τµ + 4ν with the ATLAS Detector. — •Alessandro Manfredini1, Sandra Kortner1, Hubert Kroha1, and Matthew Backingham21Max-Planck-Institut Fuer Physik, Muenchen, Deutschland — 2University of Washington, Washington D.C. US

Discovering the mechanism responsible for electroweak symmetry-breaking and the origin of mass for elementary particles has been one of the major goals of the physics program at the Large Hadron Collider. The recent discovery of a Higgs boson at the LHC is also compatible with several extension of the Standard Model, in particular with Supersymmetric scenarios. In the Minimal Supersymmetric extesion of the Standard Model (MSSM) the Higgs sector is composed of two Higgs doublets of opposite hypercharge resulting in five observable Higgs bosons, two charged and three neutral. In this talk a search for neutral MSSM Higgs bosons with the ATLAS detector at the LHC is presented based on proton-proton collisions at a center-of-mass energy of 8 TeV corresponding to an integrated luminosity of 20 fb−1. We consider Higgs decays into τ lepton pairs with subsequent decays of the τ leptons into electron or muon. Due to the reduced QCD background this search can compete with searches in hadron-hadron and lepton-hadron final states and is of particular importance for low-mass Higgs searches.
