在OPERA实验中寻找出现模中的νμ { \to } ντ振荡

Search for νμ {\to} ντ oscillations in appearance mode in the OPERA experiment

L. S. Esposito

摘要:

OPERA实验旨在通过研究νμ { \tp } ντ通道首次直接探测中微子振荡的出现模式。OPERA探测器位于距离中微子源730 km的CNGS长基线νμ束中。对2008-2009年运行中采集的数据进行的次级抽样分析已经完成。在简单描述了光束和实验装置后,我们报告了事件分析和第一个候选事件,其背景估计和统计意义。

英文摘要:

The OPERA experiment is aiming at the first direct detection of neutrino oscillations in appearance mode through the study of the νμ {\tp} ντ channel. The OPERA detector is placed in the CNGS long baseline νμ beam 730 km away from the neutrino source. The analysis of a sub-sample of the data taken in the 2008-2009 runs was completed. After a brief description of the beam and the experimental setup, we report on event analysis and on a first candidate event, its background estimation and statistical significance.
