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

KM3NeT/ORCA is currently under construction in the Mediterranean Sea. It has been designed to detect atmospheric neutrinos with energies lower than 100 GeV. For this, a three dimensional grid of photomultiplier tubes (PMTs) detects the Cherenkov radiation emitted by particles that result from neutrino interactions with matter. The assessment of the data recorded by the detector is performed by comparisons to Monte Carlo simulations, which include the state of the art knowledge about all the physical processes involved in the production of the detected signals. The so-called neutrino generators employ different approximations to simulate the distribution of final state particles produced in neutrino interactions. KM3BUU is an implementation of the GIBUU generator for the KM3NeT detector, which is currently under development. In this talk, the status of KM3BUU is presented, as well as a comparison to an implementation of the GENIE generator in KM3NeT.
