摘要:

中微子磁矩大于$10^{-19}μ_B$的测量结果将是一个明显的物理信号,超越了标准模型,而不是存在大质量狄拉克中微子。利用在这种技术上取得的进展来研究暗物质和无中微子双β衰变,在核反应堆附近使用充满40巴气体的球形正比计数器探测器将是进行这种测量的一种简单方法。只需更换气体就可以使用不同的靶:氙、CF $_4$和氩进行了比较,一年数据采集的灵敏度分别达到了$4.3 \times 10^{-12} μ_B$、$6.5 \times 10^{-12} μ_B$和$8.5 \times 10^{-12} μ_B$的水平。

英文摘要:

The measurement of neutrino magnetic moment larger than $10^{-19}μ_B$ would be a clear signature of physics beyond the standard model other than the existence of massive Dirac neutrinos. The use of a spherical proportional counter detector filled with gas at 40 bar located near a nuclear reactor would be a simple way to perform such a measurement exploiting the developments made on such a technology for the search of dark matter and neutrinoless double beta decay. Different targets can be used just by replacing the gas: xenon, CF$_4$ and argon were compared and the sensitivity in one year of data taking could reach the level of $4.3 \times 10^{-12} μ_B$, $6.5 \times 10^{-12} μ_B$, and $8.5 \times 10^{-12} μ_B$, respectively.
