摘要:

MiniBooNE和SciBooNE合作报告了在费米实验室的助推器中微子束线上联合搜索短基线消失的\bar{ν_μ}的结果。MiniBooNE Cherenkov探测器和SciBooNE跟踪探测器从同一束中观察反中微子,因此对它们的数据集进行综合分析可以部分限制一些通量和截面的不确定性。在ν_μ背景中的不散射受到中微子通量和在两个探测器上进行的截面测量的限制。使用似然比方法设定\bar{ν_μ}消失的90%置信水平上限,该上限显著改善了Δ m^2 = 0.1 - 100 eV^2区域的先前限值。

英文摘要:

The MiniBooNE and SciBooNE collaborations report the results of a joint search for short baseline disappearance of \bar{ν_μ} at Fermilab's Booster Neutrino Beamline. The MiniBooNE Cherenkov detector and the SciBooNE tracking detector observe antineutrinos from the same beam, therefore the combined analysis of their datasets serves to partially constrain some of the flux and cross section uncertainties. Uncertainties in the ν_μ background were constrained by neutrino flux and cross section measurements performed in both detectors. A likelihood ratio method was used to set a 90% confidence level upper limit on \bar{ν_μ} disappearance that dramatically improves upon prior limits in the Δm^2=0.1-100 eV^2 region.
