摘要:

利用ANTARES中微子望远镜在2007年和2008年期间记录的数据,对来自太阳方向的高能中微子进行了搜索。中微子选择标准的选择是为了最大限度地选择可能产生的信号,这些信号是积累在太阳中心的大质量弱相互作用粒子相对于大气背景的自湮灭产生的。在数据揭盲后,观测到的朝向太阳的中微子数量与背景预期相符。$90\%$ CL上限的自旋相关和自旋无关的WIMP质子截面的推导和比较两个超对称模型,CMSSM和MSSM-7的预测。ANTARES的限制与其他中微子天文台所获得的竞争力和更严格的比直接搜索实验所获得的自旋相关的WIMP质子截面。

英文摘要:

A search for high-energy neutrinos coming from the direction of the Sun has been performed using the data recorded by the ANTARES neutrino telescope during 2007 and 2008. The neutrino selection criteria have been chosen to maximize the selection of possible signals produced by the self-annihilation of weakly interacting massive particles accumulated in the centre of the Sun with respect to the atmospheric background. After data unblinding, the number of neutrinos observed towards the Sun was found to be compatible with background expectations. The $90\%$ CL upper limits in terms of spin-dependent and spin-independent WIMP-proton cross-sections are derived and compared to predictions of two supersymmetric models, CMSSM and MSSM-7. The ANTARES limits are competitive with those obtained by other neutrino observatories and are more stringent than those obtained by direct search experiments for the spin-dependent WIMP-proton cross-section.
