用IceCube 22弦探测器对太阳中性伴子湮灭产生的μ子通量的限制

Limits on a muon flux from neutralino annihilations in the Sun with the IceCube 22-string detector

IceCube collaboration, R. Abbasi

摘要:

利用IceCube 22弦中微子探测器在2007年收集的104.3天的生存时间的数据,在太阳中性中微子湮灭中搜索μ子中微子。没有观察到超过预期大气背景的过量。上限已获得的湮灭率的捕获中性中子在太阳和转换到限制的WIMP质子截面的WIMP质量在250 - 5000 GeV的范围内。这些结果是迄今为止对中性伴子在太阳中湮灭的最严格限制。

英文摘要:

A search for muon neutrinos from neutralino annihilations in the Sun has been performed with the IceCube 22-string neutrino detector using data collected in 104.3 days of live-time in 2007. No excess over the expected atmospheric background has been observed. Upper limits have been obtained on the annihilation rate of captured neutralinos in the Sun and converted to limits on the WIMP-proton cross-sections for WIMP masses in the range 250 - 5000 GeV. These results are the most stringent limits to date on neutralino annihilation in the Sun.
