nu_e在MiniBooNE中消失

nu_e Disappearance in MiniBooNE

Carlo Giunti, Marco Laveder

摘要:

MiniBooNE实验中测量到的低能nu_e事件的异常过剩,用束流中绝对中微子通量的重正化和nu_e的同时消失来解释,这与镓放射源实验的结果是一致的。本文给出了MiniBooNE数据的拟合结果(P(nu_e->nu_e)= 0.64 + 0.08 - 0.07),以及MiniBooNE数据与镓源实验测量的nu_e消失的联合拟合结果(P(nu_e->nu_e)= 0.82 +-0.04)。我们还表明,我们对数据的解释也与从束流收集器实验结果的分析中发现的有利于nu_e消失的旧指示相一致,导致P(nu_e->nu_e)= 0.80 + 0.03 - 0.04。

英文摘要:

The anomalous excess of low-energy nu_e events measured in the MiniBooNE experiment is explained through a renormalization of the absolute neutrino flux and a simultaneous disappearance of the nu_e's in the beam, which is compatible with that indicated by the results of Gallium radioactive source experiments. We present the results of the fit of MiniBooNE data (P(nu_e->nu_e) = 0.64 +0.08 -0.07) and the combined fit of MiniBooNE data and the nu_e disappearance measured in the Gallium radioactive source experiments, which gives P(nu_e->nu_e) = 0.82 +- 0.04. We show that our interpretation of the data is also compatible with an old indication in favor of nu_e disappearance found from the analysis of the results of beam-dump experiments, leading to P(nu_e->nu_e) = 0.80 +0.03 -0.04.
