Abstract
Data collected at the LHC are analyzed by the ATLAS collaboration for evidence
of dark matter. In this thesis, a fast simulation of the ATLAS detector response using
the Delphes software is assessed for dark matter models with a leptonically decaying
Z boson and a pair of dark matter particles in the final state. Limits for the Two
Higgs Doublet plus pseudoscalar dark matter model are obtained using simplified
systematics, and found to be nearly indistinguishable to limits obtained using the
more complex standard ATLAS analysis.
