ANTARES中微子望远镜的初步结果

First results from the ANTARES neutrino telescope

Th. Eberl

摘要:

ANTARES探测器是观测南方天空最灵敏的中微子望远镜,也是世界上第一个在深海运行的粒子探测器。它安装在地中海2475米的深度。作为早期结果的一个例子,大气μ介子通量的测定进行了讨论,并与以前的测量发现一个很好的协议。此外,搜索超过大气中微子通量的高能量事件的结果报告和显着的限制设置在多TeV到PeV的能量范围内的扩散宇宙中微子通量。使用800多天的有效数据采集的数据,部分在建设阶段,第一次分析搜索点状过剩的中微子天空分布已经执行。所得到的灵敏度ANTARES的报告,并与其他探测器的测量。本文介绍了2008年4月首次从费米探测到的伽玛耀斑中寻找中微子的方法和结果。没有发现超过大气背景预期的显著中微子信号。

英文摘要:

The ANTARES detector is the most sensitive neutrino telescope observing the southern sky and the world's first particle detector operating in the deep sea. It is installed in the Mediterranean Sea at a depth of 2475 m. As an example of early results, the determination of the atmospheric muon flux is discussed and a good agreement with previous measurements is found. Furthermore, the results of a search for high-energy events in excess of the atmospheric neutrino flux are reported and significant limits are set on the diffuse cosmic neutrino flux in the multi-TeV to PeV energy range. Using data from more than 800 days of effective data taking, partly during the construction phase, a first analysis searching for point-like excesses in the neutrino sky distribution has been performed. The resulting sensitivity of ANTARES is reported and compared to measurements of other detectors. A method employed for a first search for neutrinos from Fermi-detected gamma-ray flaring blazars in the last 4 months of 2008 is described and the results are reported. No significant neutrino signal in excess of that expected from atmospheric background has been found.
