Cambridge Supersymmetry Working Group

Our aim is to investigate the observability of SUSY signals with the ATLAS detector.
We make use of the HERWIG event generator, interfaced to the ATLAS fast simulation for
most of our studies.

Among our current studies are:

- detection of sleptons in superstring inspired models of SUSY breaking
- detection of neutralino decays in R-parity violation models
- the observability of charginos in models with Anomaly-Mediated SUSY breaking
- signatures for large and small extra dimensions
- studies to establish the experimental reach in terms of fine tuning:
                can models with small fine-tuning evade detection?

This page contains documents published by members of the group relating to our SUSY studies.
