GiBUU release notes


We do not publish every revision of the code. Especially we retain parts of the code representing ongoing doctoral theses or other unpublished work. Therefore results published by our group may not (yet) be reproducible by the public releases below.

GiBUU 2021 (08.02.2021) [svn r7938]

  • Option: collisional broadening of rho-meson spectral function consistent with collision term of the transport equation (
  • Option: enhanced dilepton radiation in np collisions agree with phenomenological inclusive e+e- invariant mass spectrum from dp collisions at 1.25A GeV (
