Description
The coherent elastic scattering of solar, diffuse supernova and atmospheric neutrinos on nuclei (CEνNS) represents the ultimate background for weakly-interacting massive particle (WIMP) detection in the GeV mass region. With the first detection of CEνNS only five years ago, these neutrinos represent a signal in themselves. Solar $^{8}\text{B}$ neutrinos are expected to be observed by the current generation of experiments, which would mark the first measurement of CEνNS from a natural source. XENONnT is one of these experiments. It has been taking science data since 2021 and recently published first results on low-energy electronic recoil signals and WIMPs. In this talk, I will present the experiment and outline the analysis effort for the first detection of solar $^{8}\text{B}$ CEνNS. Special emphasis is put on lowering the detection threshold of the detector and on the control of backgrounds near the threshold as prerequisites for a solar CEνNS detection. The current status of the search will be summarized.
