Search for squarks and gluinos in final states with jets and missing transverse momentum with the ATLAS detector — •Veronika Magerl — Albert-Ludwigs-Universität Freiburg
Many extensions of the Standard Model (SM) include heavy coloured particles, such as the squarks and gluinos of supersymmetric (SUSY) theories, which could be accessible at the Large Hadron Collider (LHC) and detected by ATLAS. A large number of R-parity-conserving models predict squarks and gluinos produced in pairs and decaying either directly or in cascades to quarks, neutralinos and eventually leptons.
The neutralino χ10 is assumed to be the Lightest Supersymmetric Particle (LSP) which escapes undetected, resulting in large missing transverse momentum which, in addition to the jets originating from the quark fragmentation, form the final states investigated in the 0-Lepton SUSY analysis. In order to distinguish these signatures from the SM background it is crucial to have a good estimation of the SM processes resulting in the same final states.
This talk presents the latest results of the ATLAS 0-Lepton SUSY analysis focusing on the techniques of background estimation.
