Search for supersymmetry with the ATLAS detector at s=13 TeV in final states with tau leptons and b-quarksMichael Holzbock, Ferdinand Krieter, Alexander Mann, and •Balthasar Schachtner — LMU München, Am Coulombwall 1, DE-85748 Garching

Supersymmetry introduces a symmetry between fermions and bosons giving rise to so-called superpartners which can solve the hierarchy problem and provide a natural candidate for dark matter. A search for supersymmetry with final states including tau leptons and jets originating from b-quarks with the ATLAS detector is presented. It includes data taken with the LHC at a center-of-mass energy of 13 TeV in 2015 and 2016 with an integrated luminosity of about 37 fb−1.

The analysis targets the direct production of scalar top quarks which decay to scalar taus, b-quarks and neutrinos. The scalar taus decay subsequently to gravitinos and Standard Model (SM) taus. The considered signature contains a light lepton from the tau decay and a hadronic tau, as well as two jets from b-quarks and missing transverse energy from the gravitinos and SM neutrinos. The main background arises from top quark production, possibly with jets misidentified as taus.
