论文摘要

太阳大气中微子(SA $ν$ S)是由宇宙射线与太阳介质的相互作用产生的。 SA $ν$ S的检测将提供有关主要宇宙射线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暗物质对太阳的不可还原背景的来源,并且测量其通量将可以更好地评估与这些搜索相关的不确定性。在本文中,我们报告了基于无线可能性最大化的分析,以与Antares Neutrino望远镜一起搜索Sa $ν$。在分析了11年内收集的数据后,找不到太阳大气中微子信号的证据。已经获得了90 \%置信度在太阳大气中微子的通量上的上限,等于7 $ \ times $$ $$ 10^{ - 11} $ [TEV $^{ - 1} $ cm $^{ - 2} $ s $ s $ s $ s $^{ - 1} $在e $_ν= $ 1 tev for Cosmic cosmic模型中,

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.
