摘要

我们探讨了在未来的NaI(Tl)暗物质探测实验中测量太阳和超新星中微子的相干弹性中微子核散射的前景。考虑到NaI(Tl)晶体降低了背景，提高了产光率，银河系内的超新星中微子的观测灵敏度大于3σ。在太阳中微子的情况下，1吨NaI(Tl)实验假设一个数量级的背景降低，5个光电子阈值和5年的数据暴露，大约3σ观测是边缘的。

Sensitivities for coherent elastic scattering of solar and supernova neutrinos with future NaI(Tl) dark matter search detectors of COSINE-200/1T

We investigate the prospects for measuring the coherent elastic neutrino–nucleus scattering of solar and supernova neutrinos in future NaI(Tl) dark matter detection experiments. Considering the reduced background and improved light yield of the recently developed NaI(Tl) crystals, more than 3 $σ$ observation sensitivities of the supernova neutrino within the Milky Way are demonstrated. In the case of the solar neutrino, approximately 3 $σ$ observations are marginal with a 1 ton NaI(Tl) experiment assuming an order of magnitude reduced background, five photoelectron thresholds, and 5-year data exposure.
