Search for supersymmetry in all-hadronic events with tau leptons

A search for physics beyond the Standard Model with highly energetic jets, large momentum imbalance, and opposite-sign tau pairs in the final state is performed using data samples with integrated luminosities of 1~fb$^{-1}$ of $pp$ collisions at $\sqrt{s}=7$~TeV collected with the CMS detector at the LHC at CERN. The Standard Model backgrounds are estimated using data--driven techniques. The number of observed events is in good agreement with the predictions for Standard Model background processes and upper limits are set in the context of models of supersymmetry.
