摘要:

太阳大气中微子(SA $ν$ s)是由宇宙射线与太阳介质相互作用产生的。SA $ν$ s的探测将提供关于初级宇宙射线的组成以及太阳密度的有用信息。这些中微子代表了间接搜索太阳暗物质的背景的一个不可减少的来源,测量它们的通量将允许更好地评估与这些搜索有关的不确定性。在本文中,我们报告的分析进行的基础上,未分组的似然最大化,寻找SA $ν$的ANTARES中微子望远镜。对11年来收集到的数据进行分析,没有发现太阳大气中微子信号的证据,得到了太阳大气中微子通量的上限,在90%置信水平下,它等于7个$\times$ $10^{-11}$ [TeV $^{-1}$ cm $^{-2}$ s $^{-1}$ ](E $_ν=$ 1 TeV)。

英文摘要:

Solar Atmospheric Neutrinos (SA$ν$s) are produced by the interaction of cosmic rays with the solar medium. The detection of SA$ν$s would provide useful information on the composition of primary cosmic rays as well as the solar density. These neutrinos represent an irreducible source of background for indirect searches for dark matter towards the Sun and the measurement of their flux would allow for a better assessment of the uncertainties related to these searches. In this paper we report on the analysis performed, based on an unbinned likelihood maximisation, to search for SA$ν$s with the ANTARES neutrino telescope. After analysing the data collected over 11 years, no evidence for a solar atmospheric neutrino signal has been found. An upper limit at 90\% confidence level on the flux of solar atmospheric neutrinos has been obtained, equal to 7$\times$$10^{-11}$ [TeV$^{-1}$cm$^{-2}$s$^{-1}$] at E$_ν=$ 1 TeV for the reference cosmic ray model assumed.
