The GiBUU project
The GiBUU project is aiming to provide an unified transport framework in the MeV and GeV energy regimes for
- elementary reactions on nuclei, as e.g.
- electron + A,
- photon + A,
- neutrino + A ,
- hadron + A (especially pion + A and proton + A)
- and for heavy-ion collisions.
For those reactions, the flow of particles is modelled within a Boltzmann-Uehling-Uhlenbeck (BUU) framework. The relevant degrees of freedom are mesons and baryons, which propagate in mean fields and scatter according to cross sections which are tuned to the energy range of 10 MeV to more than 10 GeV. In the higher energy regimes the concept of pre-hadronic interactions is implemented in order to realize color transparancy and formation time effects. For a general overview of the model, please refer to our recent review paper:

The numerical implementation, named GiBUU (aka The Giessen BUU Project), is written in modular Fortran 2003 and based upon a Subversion version control system, which allows for a concise control over the full development phase of the code.
The history of the code is rather long and reports about several main development steps. The present initiative accomplished a total rewrite of the source code in a present-day computing language. The main goals of this effort were modularization to allow for a more transparent multi-user development process, a strict reduction of global variables for a more transparent debugging procedure, an improved control over the development phase such that modifications can be backtracked and a unified standard version. Therefore every member of the team works on the same single code version, albeit different temporal branches may coexist. Possible technical overhead is compensated by the benefit of a faster distribution of improvements and innovations and their enhanced sustainability.
