A bottom-up approach to SUSY analyses

This paper proposes a new way to perform event generation and analysis in searches for new physics at the LHC. An abstract notation is used to describe the new particles on a level which better corresponds to detector resolution of LHC experiments. In this way the SUSY discovery space can be decomposed into a small number of eigenmodes each with only a few parameters, which allows us to investigate the SUSY parameter space in a model-independent way. By focusing on the experimental observables for each process investigated, the bottom-up approach allows us to systematically study the boarders of the experimental efficiencies and thus to extend the sensitivity for new physics.
