Dilepton production at SIS energies

In this short review the results of detailed studies for dilepton production from p + A and A + A reactions at SIS energies are presented. The calculations are based on a semi-classical BUU transport model that includes the off-shell propagation of vector mesons and evaluates the width of the vector mesons dynamically. Different scenarios of in-medium modifications of vector mesons, such as col...

We analyse the production and propagation of pions and kaons in heavy-ion reactions from 0.8 – 1.8 A·GeV within a coupled channel transport approach including the kaon production channels BB K. Assuming the hyperon selfenergy to be 2/3 of the nucleon selfenergy we find that all inclusive experimental K + spectra at SIS energies can be reproduced reasonably well without any selfenergies for the ...
