Abstract
In this thesis we present the implementation of a fast simulation code for the interaction of high energy radiation with matter. The method used is based on a parametrization of the average shape of the electromagnetic and hadronic showers and on the Monte Carlo Method. We show that the code is accurate by satisfactorily reproducing the basic characteristics of the SLD calorimeter's response to showers. Then we give some examples of the application of the code to the analysis of the decay of the weak neutral boson. We measure the angular distribution of the decay products. We show that the identification of the jet's flavour or quark's type is very difficult through an analysis of the sphericity and the aplanarity of the event . We calculate the intrinsic missing energy resolution of the detector and how well the direction of the missing energy can be used to obtain the direction of highly penetrating particles. We also discuss a method used to improve the performance of the calorimeter. This code will be extensively used for the simulation of the SLD experiment.
