Neutrino Geoscience workshop 2026 Zhuhai

Large liquid xenon detectors developed for dark matter searches combine substantial target masses with excellent background control, offering a versatile platform for rare event physics. XENONnT’s exceptionally low background and low energy threshold have enabled its emergence as an observatory for solar neutrinos. I will present recent measurements of elastic scattering of neutrinos on electrons and coherent elastic scattering of neutrinos on nuclei, probing solar pp and $^8B$ neutrinos through complementary electronic and nuclear recoil channels. These results open new opportunities for precision electroweak and neutrino physics, while informing the development of future geoneutrino detection strategies.
