Estimate of the electronic and nuclear recoil background in DARWIN: — •Antoine Chauvin, Maike Doerenkamp, Andrii Terliuk, and Stephanie Hansmann-Menzemer — Universität Heidelberg

The DARWIN experiment is a proposed future Direct Dark Matter observatory that aims to detect WIMPs through WIMP-nucleus interactions, in a multi-ton liquid xenon TPC. Its goal is to become the most sensitive experiment to WIMP-nucleus interaction. To estimate this sensitivity, good models for signal and background generation, and of the detection processes are fundamental. In this talk, we will report on the simulation of the response of the DARWIN detector to different background sources, interacting both through Electronic Recoil and Nuclear Recoil. We compare these to the response of a WIMP signal and derive according estimates for the WIMP sensitivity of the DARWIN experiment.
