双中微子反应堆中微子实验

The Double Chooz reactor neutrino experiment

I. Gil-Botella

摘要:

双π z反应堆中微子实验将是下一个探测器,以前所未有的灵敏度寻找非零θ 13混合角,这可能会打开揭示CP破坏在轻子部门的方式。这个角度的测量将基于两个位于离法国的Bronz核反应堆堆芯不同距离的相同探测器上的反中微子光谱的精确比较。双折射率是特别有吸引力的,因为它能够测量sin 2(2 θ 13)到3 σ,如果sin 2(2 θ 13)> 0.05,或排除sin 2(2 θ 13)下降到0.03,在90% C. L。对于Dm 2 = 2.5 x 10-3 eV 2,使用两个探测器采集三年的数据。远探测器的建造将于2008年开始,预计2009年将获得第一个中微子结果。本文综述了该实验的现状、物理潜力、探测器的设计和预期性能。

英文摘要:

The Double Chooz reactor neutrino experiment will be the next detector to search for a non vanishing theta13 mixing angle with unprecedented sensitivity, which might open the way to unveiling CP violation in the leptonic sector. The measurement of this angle will be based in a precise comparison of the antineutrino spectrum at two identical detectors located at different distances from the Chooz nuclear reactor cores in France. Double Chooz is particularly attractive because of its capability to measure sin2(2theta13) to 3 sigmas if sin2(2theta13) > 0.05 or to exclude sin2(2theta13) down to 0.03 at 90% C.L. for Dm2 = 2.5 x 10-3 eV2 in three years of data taking with both detectors. The construction of the far detector starts in 2008 and the first neutrino results are expected in 2009. The current status of the experiment, its physics potential and design and expected performance of the detector are reviewed.
