Current Status of ANNIE Monte Carlo — •Johann Martyn, Amala Augusthy, Noah Goehlke, Philipp Kern, David Maksimovic, Daniel Tobias Schmid, Michel Wurm, and Dorina Carolin Zundel for the ANNIE collaboration — Johannes Gutenberg-Universität, Institut für Physik, Mainz 55128, Germany

The Accelerator Neutrino Neutron Interaction Experiment (ANNIE) is a 26-ton water Cherenkov neutrino detector installed on the Booster Neutrino Beam (BNB) at Fermilab. Its main physics goals are to perform a measurement of the neutron yield from neutrino-nucleus interactions, as well as a measurement of the charged-current cross section of muon neutrinos. Additionally, ANNIE has strong focus on the research and development of new detector technologies and target media, such as Large Area Picosecond Photodetectors (LAPPDs) and Water-based Liquid Scintillator (WbLS). Ratpac is a simulation and analysis framework build with GEANT4, ROOT, and C++, which is currently used by multiple experiments in the investigation of WbLS. In ANNIE Ratpac simulates the full detector response, including the WbLS and LAPPDs. This talk presents the current status of the ANNIE implementation in Ratpac. his work is supported by the DFG.
