Abstract.

We have developed a versatile software package for the simulation of di-electron production in pp and dp collisions at moderate beam kinetic energies (1-2GeV). Particular attention has been paid to incorporate different descriptions of the Dalitz decay \( \Delta\)\( \rightarrow\)Ne+e- via a common interface. In addition, suitable parameterizations for the virtual bremsstrahlung process NN\( \rightarrow\)NNe+e- based on one-boson exchange models have been implemented. Such simulation tools with high flexibility of the framework are important for the interpretation of the di-electron data taken with the HADES spectrometer and demonstrates the wide applicability within the field of nuclear and hadronic physics.
