XENONnT Optical Model — •Kai Böse for XENONnT — Max-Planck-Institut für Kernphysik, Heidelberg, Germany

XENONnT is one of the world leading direct detection experiments aiming to find or exclude dark matter candidates, especially the WIMP. The experiment is located at the Gran Sasso Underground Lab, where 8.5 tons of the target material xenon are shielded from cosmic radiation.

Particles (potentially including dark matter) recoil in the target with the xenon atoms, resulting in scintillation light. Before being detected by photomultipliers at the top and bottom of the setup, the light scatters with the xenon, can be absorbed by impurities or reflected on surfaces. This talk covers our optical model which describes how light behaves in the detector and how it is used to simulate our signals.
