Estimation of electronic recoil leakage into nuclear recoil signal for DARWIN — •Antoine Chauvin, Maike Doerenkamp, Andrii Terliuk, and Stephanie Hansmann-Menzemer — Physikalisches Institut, Universität Heidelberg

The DARWIN experiment is a proposed future Direct Dark Matter detector which aims to detect WIMPs through WIMP-nucleus interactions, in a multi-ton liquid xenon target. Is 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. Electronic Recoil (ER) processes are the dominant background. Thus a good rejection of ER background, and an estimation of the ER leakage in Nuclear Recoil (NR) signal, is fundamental to achieve a high sensitivity. In this talk, I will report on the setup of a simulation of the DARWIN detection process, and its use to estimate the ER leakage fraction.
