Neutrino physics with multi-ton scale liquid xenon detectors

摘要: We study the sensitivity of large-scale xenon detectors to low-energy solar neutrinos, coherent neutrino-nucleus scattering and neutrinoless double beta decay. As a concrete example, we consider part proposed DARWIN (Dark Matter WIMP Search with Noble Liquids) experiment. perform detailed Monte Carlo simulations expected backgrounds, considering realistic energy resolutions thresholds in detector. In window 2-30 keV, where pp $^7$Be-neutrinos is highest, an integrated pp-neutrino rate 5900 events can be reached fiducial mass 14 tons natural xenon, after 5 years data. The flux could thus measured statistical uncertainty around 1%, reaching precision model predictions. These neutrinos will limiting background dark matter search channel for WIMP-nucleon cross sections below $\sim$2$\times$10$^{-48}$ cm$^2$ masses 50 GeV$\cdot$c$^{-2}$, assumed 99.5% rejection electronic recoils due elastic neutrino-electron scatters. Nuclear from limit $\sim$6 GeV$\cdot$c$^{-2}$ above $\sim$4$\times$10$^{-45}$cm$^2$. reach competitive half-life 5.6$\times$10$^{26}$ y decay $^{136}$Xe data, using 6 central detector region.
