短基线抗持续振荡->抗持续振荡

Short-Baseline antinu_mu -> antinu_e Oscillations

Carlo Giunti, Marco Laveder

摘要:

我们分析了MiniBooNE短基线实验的antinu_mu -> antinu_e振荡的最新结果,在反中微子混合的极小模型独立的框架结合积极的LSND信号和负KARMEN测量。我们证明了三个短基线antinu_mu -> antinu_e实验的数据是相容的。考虑到由于反应堆反中微子实验中得到的短基线反连续消失的限制而引起的与模型无关的约束,我们发现有效振荡参数的有利区域位于0.002 <~ sin ^2 2 θ <~ 0.05和0.2 <~ Δ m^2 <~ 2 eV ^2之间。

英文摘要:

We analyze the recent results of the MiniBooNE short-baseline experiment on antinu_mu -> antinu_e oscillations in a minimal model-independent framework of antineutrino mixing in conjunction with the positive LSND signal and the negative KARMEN measurements. We show that the data of the three short-baseline antinu_mu -> antinu_e experiments are compatible. Taking into account also the model-independent constraints due to the limits on short-baseline antinu_e disappearance obtained in reactor antineutrino experiments, we find that the favored region of the effective oscillation parameters lies within 0.002 <~ sin^2 2 theta <~ 0.05 and 0.2 <~ Delta m^2 <~ 2 eV^2.
