    4 The '''GiBUU project''' is aiming to provide an unified transport framework in the MeV and GeV energy regimes for
    5  * '''elementary reactions on nuclei''', as e.g.
    6     * '''electron''' + A,
    7     * '''photon''' + A,
    8     * '''neutrino''' + A ,
    9     * '''hadron''' + A (especially '''pion''' + A)
     3This is just a page to practice and learn WikiFormatting.

    11  * and for '''heavy-ion collisions'''.
    12 
    13 For those reactions, the flow of particles is modelled within a [wiki:physicsInput Boltzmann-Uehling-Uhlenbeck (BUU) framework].
    14 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.
    15 
    16 The new numerical implementation, named '''GiBUU''' (standing for '''Gießen''' and '''BUU'''), is written in modular [http://www.kcl.ac.uk/kis/support/cit/fortran Fortran2003] and based upon a [http://subversion.tigris.org/ Subversion] version control system, which allows for a concise control over the full development phase of the code.
    17 
    18 The [wiki:GiBUU_Code_history 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''.
    19 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''.
    20 
    21 GiBUU is being developed at the [http://theorie.physik.uni-giessen.de Institut für Theoretische Physik] of the [http://www.uni-giessen.de Justus-Liebig-Universität Gießen].
