Search for electroweak production of supersymmetric particles in final states with at least two hadronically decaying taus and missing transverse momentum with the ATLAS detector in proton-proton collisions at $\sqrt{s}$= 8 TeV

A search for the production of weakly coupled supersymmetric particle decaying into final states with at least two hadronically decaying taus and missing transverse momentum is presented in this poster. The complete 2012 data sample of $\sqrt{s}$ = 8 TeV proton-proton collisions is used in the analysis, which was recorded with the ATLAS detector at the CERN Large Hadron Collider cor- responding to a total integrated luminosity of 20.7 $fb^{−1}$. Exclusion limit at 95% confidence level are derived in the context of the phenomenological Minimal Supersymmetric Standard Model and Simplified Model, characterized by the presence of low mass staus.
