GiBUU based neutrino interaction simulations in KM3NeT

The simulation of the neutrino interaction is a crucial step in the simulation chain of a neutrino experiment. The different processes taking part in the neutrino scattering on a nucleus require several approximations in order to make the simulation possible and to realize reasonable computation times. This can be realised in different ways, e.g. by parametrised models for the different scattering processes and energy regimes as it is implemented in GENIE. The GiBUU neutrino generator utilises the Boltzmann-Uehling-Uhlenbeck equation to simulate the particle flow after the neutrino interactions, the so-called final state interactions. The detector-specific results in form of the visible energy in the detector after the light propagation simulation and the KM3NeT event reconstruction are presented. In addition to that, the comparison to the GENIE based simulation environment in KM3NeT (gSeaGen) is drawn.
