Abstract
The cascade mass reconstruction approach was used for mass reconstruction of the lightest \( \tilde \tau \) produced at the LHC in the cascade decay \( \tilde g \to \tilde bb \to \tilde \chi _2^0 bb \to \tilde \tau _1 \tau bb \to \tilde \chi _1^0 \tau \tau bb \). The \( \tilde \tau _1 \) mass was reconstructed assuming that masses of gluino, bottom squark, and two lightest neutralinos were reconstructed in advance. SUSY data sample sets for the SU(3) model point containing 160k events each were generated which corresponded to an integrated luminosity of about 8 fb−1 at 14 TeV. These events were passed through the AcerDET detector simulator, which parametrized the response of a generic LHC detector. The mass of the \( \tilde \tau _1 \) was reconstructed with a precision of about 20% on average.
