  <dc:description>The Standard Model of particle physics (SM) is the theory used to describe both the fundamental constituents of matter and the fundamental interactions. While being very successful in describing the observed phenomena, it leaves some questions unanswered. Extensions to the SM such as the Minimal Supersymmetric extension to the Standard Model (MSSM) qualify for solving these open questions. A promising signal channel to test the MSSM is the decay of an additional neutral Higgs boson into two τ -leptons. For signal extraction, important background processes such as the decay of the Z boson into two τ -leptons need to be understood. In this thesis, the development and the application of the embedding method are described. This data-driven method is developed to improve the modeling of Z → τ τ events at the CMS detector. Embedded events are used to search for a heavy neutral Higgs boson in the context of the MSSM. The results presented in this thesis serve as a cross-check of the background description by simulated Z → τ τ events that is used for the results published by the CMS collaboration.
