中微子背景对暗物质的影响

Neutrino Backgrounds to Dark Matter Searches

Jocelyn Monroe, Peter Fisher

摘要:

中微子相干散射截面可以大到10^{-39} cm ^2,而目前的暗物质实验对弱相互作用相干散射截面的灵敏度要小5个数量级;未来的实验计划对小到10^{-48} cm ^2的截面的灵敏度。由于太阳中微子的中性流相干散射具有较大的目标质量和较小的反冲能探测阈值,因此成为暗物质研究中不可或缺的背景。在当前的零背景分析范式中,中微子相干散射将限制暗物质散射截面的可实现灵敏度,在10^{-46} cm ^2的水平。

英文摘要:

Neutrino coherent scattering cross sections can be as large as 10^{-39} cm^2, while current dark matter experiments have sensitivities to WIMP coherent scattering cross sections five orders of magnitude smaller; future experiments plan to have sensitivities to cross sections as small as 10^{-48} cm^2. With large target masses and few keV recoil energy detection thresholds, neutral current coherent scattering of solar neutrinos becomes an irreducible background in dark matter searches. In the current zero-background analysis paradigm, neutrino coherent scattering will limit the achievable sensitivity to dark matter scattering cross sections, at the level of 10^{-46} cm^2.
