Neutrino Generator Comparisons GiBUU/GENIE in KM3NeT — •Johannes Schumann for the ANTARES-KM3NET-ERLANGEN collaboration — Friedrich-Alexander-Universität Erlangen-Nürnberg

The KM3NeT neutrino telescope is currently being deployed in the Mediterranean Sea. The detector comprises a three-dimensional array of digital optical modules, which detect faint Cherenkov light signals from secondary particles of neutrino interactions. Simulations of the neutrino interactions play an important role for the interpretation of the measurements and are performed by so-called neutrino generators, which employ different approximations in order to achieve a numerical solution with reasonable computing resources. This contribution describes the comparison between GENIE, the neutrino generator used by KM3NeT and the GiBUU generator. The comparisons are performed at the level of systematic uncertainties and their impact on sensitivity estimates.
