在MINOS中首次观测到加速子μ子反中微子

First Observation of Accelerator Muon Antineutrinos in MINOS

Istvan Danko

摘要:

我们报告的第一个直接观察μ介子反中微子在MINOS远探测器在当前的μ介子中微子占主导地位的光束。利用探测器的磁场,通过识别带电电流相互作用中产生的μ子的电荷符号,逐事件分离μ子中微子和反μ子。我们目前的μ子反中微子振荡参数的初步结果,以及对中微子的分数的限制,消失和重新出现的反中微子。我们还讨论了测量的前景时,极性的磁聚焦喇叭将被逆转,以创建一个专门的μ子反中微子束。

英文摘要:

We report the first direct observation of muon antineutrinos in the MINOS Far Detector in the current muon-neutrino dominated beam. The magnetic field of the detector is utilized to separate muon neutrinos and antineutrinos event-by-event by identifying the charge sign of the muon created in charged-current interactions. We present preliminary results on the muon antineutrino oscillation parameters as well as limit on the fraction of neutrinos that disappear and reappear as antineutrinos. We also discuss the prospect of the measurement when the polarity of the magnetic focusing horns will be reversed to create a dedicated muon antineutrino beam.
