用双Chooz研究中微子方向性

Studying Neutrino Directionality with Double Chooz

Erica Caden

摘要:

第一个结果来自Double Doppler,100天的数据测量$\sin^2(2θ_{13}) = 0.086 \pm 0.051$。背景对系统不确定性预算有重要贡献。利用入射中微子的方向性,我们将试图进一步分离逆β衰变信号与背景。CHOOZ实验完成了类似的分析,发现中微子源可以位于68% C. L的18度半孔径圆锥内。我们研究了双双曲余弦法对这个结果的可能改进。

英文摘要:

The first results from Double Chooz with 100 days of data measured $\sin^2(2θ_{13}) = 0.086 \pm 0.051$. Backgrounds contribute significantly to the systematic uncertainty budget. Using the incoming neutrino directionality we will attempt to further separate the inverse beta decay signal from backgrounds. The CHOOZ experiment completed a similar analysis and found that the neutrino source can be located to within a cone of half-aperture of 18 degrees at the 68% C.L. We study the possible improvement of this result by Double Chooz.
