中微子在直接暗物质探测器上的相干散射率
Neutrino Coherent Scattering Rates at Direct Dark Matter Detectors
摘要：
中子引起的反冲事件可能构成直接暗物质搜索的背景，特别是对于那些努力达到吨级或更高的探测器。本文讨论了由于几个最重要的来源，包括太阳，大气和弥漫超新星中微子预期的中微子诱导的背景光谱。最大的速率来自$^8$ B产生的太阳中微子，在最重的核目标的所有反冲能量上，每吨年提供超过$\sim 10^3$事件。然而，预计这些$^8$ B事件中的大多数将低于现代探测器的反冲阈值。只有当WIMP-核子截面小于$10^{-12}$ pb时，剩余的中微子源才能构成WIMP诱导反冲率的背景。最后讨论了非电子中微子对扩散超新星中微子通量的敏感性，并将预测的通量极限与现有的通量极限进行了比较。
英文摘要：
Neutrino-induced recoil events may constitute a background to direct dark matter searches, particularly for those detectors that strive to reach the ton-scale and beyond. This paper discusses the expected neutrino-induced background spectrum due to several of the most important sources, including solar, atmospheric, and diffuse supernova neutrinos. The largest rate arises from $^8$B produced solar neutrinos, providing upwards of $\sim 10^3$ events per ton-year over all recoil energies for the heaviest nuclear targets. However the majority of these $^8$B events are expected to be below the recoil threshold of modern detectors. The remaining neutrino sources are found to constitute a background to the WIMP-induced recoil rate only if the WIMP-nucleon cross section is less than $10^{-12}$ pb. Finally the sensitivity to diffuse supernova neutrino flux for non-electron neutrino flavors is discussed, and projected flux limits are compared with existing flux limits.
