镓异常的统计意义

Statistical Significance of the Gallium Anomaly

Carlo Giunti, Marco Laveder

摘要:

考虑到探测截面的不确定性,计算了GALLEX和SAGE太阳中微子探测器在放射源实验中测得的电子中微子异常亏损的统计显著性。我们发现异常的统计显著性约为3.0 sigma。一个适合的数据方面的中微子振荡有利于在约2.7 σ短基线电子中微子消失相对于零假设没有振荡。

英文摘要:

We calculate the statistical significance of the anomalous deficit of electron neutrinos measured in the radioactive source experiments of the GALLEX and SAGE solar neutrino detectors taking into account the uncertainty of the detection cross section. We found that the statistical significance of the anomaly is about 3.0 sigma. A fit of the data in terms of neutrino oscillations favors at about 2.7 sigma short-baseline electron neutrino disappearance with respect to the null hypothesis of no oscillations.
