A versatile method for simulating pp -> ppe+e- and dp -> pne+e-p_spec reactions

Abstract

We have developed a versatile software package for the simulation of di-electron production in $pp$ and $dp$ collisions at SIS energies. Particular attention has been paid to incorporate different descriptions of the Dalitz decay $\Delta \to N{e}^{+}{e}^{-}$ via a common interface. In addition, suitable parameterizations for the virtual bremsstrahlung process $NN\to NN{e}^{+}{e}^{-}$ 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 the design of forthcoming experiments.
