Abstract
The main subject of this thesis is to extract the spectral function of a specific interpolating field from the OPE of its correlator. For this task, we propose to use the maximum entropy method (MEM), which allows us the obtain the spectral function without any assumptions on its functional form. How this is done, will be discussed in this chapter. Furthermore, for illustration, we will also show the results of the MEM analysis of a simple toy model.
