Jet and missing transverse momentum trigger improvements for supersymmetry signatures in 2012 with the ATLAS detector

In 2012, the LHC has been operating at a higher center-of-mass energy and higher instantaneous luminosity, compared to 2011, providing the experiments with unprecedented amounts of hadron collision data. This document summarizes how the challenge of triggering on new physics signatures, such as supersymmetry (SUSY), on the 2012 LHC data, was successfully addressed by the ATLAS experiment.
